Also, to solve @tomtomme 's issue all you really need to do is call "delete column" properly if someone erases the name. Because that was the original intended behaviour right?
You erase the name to erase the column?

I would consider this dangerous behaviour IF the undo button does not work. Because it is not intuitive that deleting the name would delete also my data. Deleting the name is something a user most probably would do by accident. So the best intended behaviour from my point of view, would be, to restore the original name OR just do nothing.
If you disagree and think the column should be deleted on erasing the name please make sure that the UNDO button works. Thx!

please make sure that the UNDO button works

Indeed, this is what I mean by "make sure it just calls deleteColumn" cause that would include the undo/redo

But I also disagree that making the name empty should remove the column: most of the time, making the name empty will be just a bad manip of the user. Trying to make it empty should reset the old name.

Ok wahtever but Im fairly sure you @boutinb are the one who added this functionality in the first place.

Ill approve it now, despite it being very ugly that the name stays empty:
