If theres already an opened file in the tile => right click works ![4_Vertical_split-png.PNG|1666x783](upload://h8ktKorLeENWBIJ571U5nzuVZSC.png) **Another Bug:** Dragging one or multiple Files to the other tile doesnt work in this case.
Thanks, this must be a bug, though I can’t reproduce. I will have to investigate.
Try to right click in the empty space, instead of clicking on the open button, to see if that makes a difference.
Your #5 I can reproduce.
