Option for more aggressive "Smart Resize"?

[Christopher-Hayes]

It would be nice if there was some way to control how aggressively "Smart Resize" is used in comparison to "Intelligent Overflow"—like a CLI option or an extension setting.

In my use, most applications just get moved to a new workspace. I then have to do a bit resizing and then move the new application back into the current workspace.

One example is if I have Firefox open to fill the screen and I open something like VLC, I expect Firefox to be resized to make space for VLC. But, VLC always gets sent to another workspace. I then have to resize Firefox and then move VLC back to the current workspace. And sometimes I have to repeat this process if I didn't resize Firefox small enough.

Monitor setup: 3 screens (2 vertical)

Making this as a discussion because it's not necessarily a bug, and preferred UX is rather opinion-based.

Thanks for the feedback!

How Smart Resize currently works:

1. The extension checks if it can shrink existing windows to make room
2. Windows can only shrink down to 30% of their original size (set by MIN_RESIZE_RATIO in constants.js)
3. If there's still not enough space after maximum shrinking, overflow kicks in.

In your Firefox + VLC scenario:

• Firefox starts at roughly 100% of the screen
• It can shrink down to about 30% minimum
• If VLC needs more than the remaining 70%, you get overflow

Why We're Being Conservative

The 30% limit is there to keep windows from becoming unusably small. Some apps (like terminals or text editors)just don't work well below a certain size.

I'm thinking of a better way to handle this, instead of having a min resize ratio. But for now, you can change it manually and rebuild Mosaic WM.

Gotcha, appreciate the response.
