The sheets bar should be configurable with some configuration options to control the ability to..
1. Add sheets
2. Remove sheets
3. Rename sheets
4. Reorder sheets
Currently we can use style hacks to hide the "insert new sheet" and "delete sheet" buttons with:
/**
* Style hacks to hide:
* 1. The undo/redo buttons in the quick-access toolbar.
* 2. The "+" add button in the sheets bar at the bottom of the spreadsheet.
* 3. The "X" remove button to remove each sheet in the sheets bar.
*/
.k-tabstrip-wrapper .k-spreadsheet-quick-access-toolbar,
.k-spreadsheet-sheets-bar-add,
.k-spreadsheet-sheets-remove {
display: none;
}
However, these settings should be available as configuration options (and possibly we can even disable/hide the sheets bar altogether similar to how the toolbars are configured at the moment).
