When using window tiling, you can only resize a window after adding a second tile. I would prefer to resize single tiles so that I can snap my window and then resize it.
Later I might open second tiles, but I don’t always so it’s a lot of workaround to add a second tile just to resize then close it.
Can you explain it with more details, maybe with a screen recording? To me it seems that “creating a tile” means splitting the screen, which already creates a “second tile”.

While recording a reply video, I discovered my understanding was flawed.
I have discovered when I drag Dolphin to a tile, I can still resize it. But when I drag firefox into a tile, I can no longer resize it - and must snap it out of it’s tile to resize.
Is there a way to alter this?
