Rounded windows in overview

[sidevesh]

Thanks for continuing the work on this!
Can you incorporate this PR I had raised earlier on the original extension based on a branch that adds rounded corners to windows in overview
yilozt#151
Without this maximized windows in overview have sharp corners and clearly we both are not fans of that :)

Sure, that looks nice. I'm planning to refactor a lot of the extension code, so I'm not adding big features for now, but after that's done I'll work on this.

Any update on this? Could it add window borders to overview as well?

@jh-devv no. See the last comment in that issue.
