Scheduler events with long duration tries to refresh view area in IE and jumps to start position of event, However it works ok in chrome, it will be great if IE also behave smoothly as we see experience in Chrome. It will make dragging events by their last edge more smoothly.

The RFC for iCal supports up to a recurrence at the second level.  While I think that is too much, you should be supporting recurrence at the minute level.

The Windows Task Scheduler supports this, as well as Linux/Unix Cron.

If you are using the Scheduler Widget as a UI for a job/task scheduling system, then having the ability to schedule at the minute level is important.

This is related to the feedback request to "Add hourly recurrence editor to Scheduler".

Refer to : http://www.telerik.com/forums/setting-recurrance-messages-from-variable

To allow multiple language support it should be possible to define the  recurrenceeditor messages in the template to use an external source rather than having to hard code 1 set of messages.

The cursor jumps on the screen (and takes no action) when you try to right click on the screen and modify an event.

Being able to highlight a specific date in the Scheduler (not necessarily today) that will be visible regardless of the view the user is using.

Scheduler should support template directives for the group header template option.

Currently you have to map every required property manually. Like this:

                model.Field("start", typeof(DateTime)).From("Start");
                model.Field("end", typeof(DateTime)).From("End");
                model.Field("title", typeof(string)).From("Title");
                model.Field("description", typeof(string)).From("Description");
                model.Field("recurrenceID", typeof(int)).From("RecurrenceID");
                model.Field("recurrenceRule", typeof(string)).From("RecurrenceRule");
                model.Field("recurrenceException", typeof(string)).From("RecurrenceException");
                model.Field("isAllDay", typeof(bool)).From("IsAllDay");
                model.Field("startTimezone", typeof(string)).From("StartTimezone");
model.Field("endTimezone", typeof(string)).From("EndTimezone");

It would be nice to be able to use the short form:

model.Field("Start");
...

The problem is not the "huge" amount of typing. What did cost me time was finding out that the SignalR version isn't working like the others.

The Scheduler allows you to add resources to the default event form. It would be nice to be able to bind these resources to objects within a custom edit template. See this forum post for more details where Alex has given a workaround.... http://www.telerik.com/forums/can-you-use-resources-for-edit-templates

please provide us the scheduler with group by date not by resource

Now sorting array is hardcoded (for example in kendo.scheduler.timelineview.js) in render method:

[
    {
        field: 'start',
        dir: 'asc'
    },
    {
        field: 'end',
        dir: 'desc'
    }
]

it will be very good if you will implement this sorting inside scheduler cell (data/group field) as parameter.

Resources could be working for an organization or multiple organizations (i.e. doctor rounding multiple hospitals). It would help to have another level or multiple levels on top of Resources so they can be filtered. 
i.e. I can select Hospital A and then select all the doctors (resources) under Hospital A and look at all schedules for that resource.

Proposal: Add a property/function that specifies the resource group to take the task's background color from.

It would be great to be able to customize the scheduler's toolbar, either by specify custom buttons and actions through 'toolbar' option or by providing a custom template.

Autoscroll when dragging an object from outside the scheduler (e.a. from a grid) is already available and works fine. It would be really nice to have this vert same functionality also available while dragging an event that's already in the scheduler...

EXRULE, RDATE recurrent rules for Sheduller as described in RFC5545

We are looking into the scheduler but it seems to be missing a feature that we would really want in a scheduler.

If you are for example in the day view, you have left the timebar and right the events. It would be nice to zoom in on the times on the left.

instead of showing events from daystart - day end you would click on a chosen starttime drag to the endtime you wish and the scheduler would zoom in on items between the selected start- endtime.

Can you add a Status Bar to scheduler appointments as per the winforms scheduler & Outlook.

Now I must write any custom logic for Event editor (such as logic for additional fields on edit form, and so on) in same angular controller, in wich global scheduler logic is placed.

When custom editor code grows and becomes huge part of this controller, I want to put this code in a separate controller.

The scheduler in week-view and day-view is always starting at 12 am. We would like to request a simple function, which allows to let the calendar scroll to the desired hour! (Let's say it is 3PM and the user would see automatically see his appointments beyond 3PM, because that is what matters and not staring at 12AM )
Nobody want to look at a day view, which starts at 12am. There are in some forums suggestions mentioned how to potentially do it, but id does not work in all screen sizes without terribly breaking it! So please please add this small, but valuable feature...
