[Feature] Overlap support

[hyoretsu]

Description

We can already define overlapping zones, even if it is a lot of pain to configure, but they don't work well when applying. They default to the bigger zone in that region.

Problem it Solves

In FancyZones a feature I used was overlapping zones, which applied them based on area covered. That allowed me to stack some 8 zones for different media formats, like a 1080p and 1440p zones in a 3440x1440 ultrawide display.

Could you possibly attach a video of the behavior? I've sort of tested it. In the editor you can move zones forward/backward. I Just haven't tested it exctensively when snapping.

I think i know what you're talking about and I had a solution. I just completely forgot to do it.

Here, I used it quite often

Try 1.15.2

At least for snapping, it didn't work. Defining zones is great, way better than FancyZones. It seems to be activating multi-zone when attaching, on inner zones whose borders touch. My modifier key is Shift, which should not be activating it.

Thank you for the json. This was super helpful. I pushed 1.15.4 and this layout is now working properly.

Working perfectly now! Thanks for bringing this great feature over to Linux. I'll post my layout in the discussion once I re-finish it. I had a pretty intricate one in PowerToys but formatted my Windows installation, but I lost it.

Welcome! Glad other people are enjoying it. I started it because I also missed FancyZones.

I got lots of stuff planned still. Next major release will be toggleable auto tiling support. Window state will be saved when swapping between snapping mode and auto tile as well.
