Not sure if this is really a bug, maybe this is just me. Can you clarify how grid editing works? I suppose it is like this:

• Long press on a cell, release and then you can move it
• Short click on a cell and you edit it

Now I know the first one is needed for mobile but it is super not intuitive on desktop. I constantly try to drag, fail, then release click around, end up in editing, etc... Sometimes i cannot move the cell to the border of the grid since those grid squares don't get selected.

Also this happened...
