Hello,
We're using the scheduler in vertical mode and we've found some potential issues/improvements for the DragCreate feature, when overlaps are not allowed.
If you try to drag create and quickly move the mouse after/before an overlapping event, the start/end time in the tooltip is updated correctly, but the event is not being resized to grow until it meets the overlapping event. This can lead to displaying a small dummy event with a lot of space until the overlapping event. This is probably done by design but I thought it's worth mentioning.
Doing the same thing also doesn't result in an overlapping error in the tooltip, but you get that error when you try to drag an existing event on top of another event. We would have expected to get the error message also in the drag create overlap scenario.
These can be reproduced in the following demo by setting allowOverlap to false: https://bryntum.com/products/scheduler/examples/vertical/
Also managed to reproduce it in horizontal mode.
Thanks in advance for checking it out!
