This call is only a nice to have, it is not critical at all. It is just a slight annoyance when building the Grid's columns - especially when there are many columns to adjust. My workflow is usually as follow.
Add all the columns needed, then after that I will run through all the columns and want to set the widths. But my speed is broken because I can't tab between the 3 width properties: Width, Min Width, Max Width. I have to click to put focus the the next value.
If possible, please can you correct the tab indexes?
PS. You may close this ticket immediately - this is only a request.
