Hi,
We've just implemented zoom levels in our scheduler pro implementation, and noticed that when the column header doesn't look great when the column doesn't have much room.
You can reproduce this in this example
https://www.bryntum.com/examples/scheduler/configuration/
by changing the zoom level to minutes and scrolling all the way to the right.
Here's a screenshot of that:
Here is a screenshot of how it looks in our implementation in our week zoom level.
Additionally, here is a screenshot of how it looks in our implementation of your ExtJS scheduler.
In the ExtJS scheduler, it just shows the start of the word, rather than aligning it centrally, which is how I think it should behave.
Thanks
Matthew Morris
