Installation was easy, and it works as expected without interfering with i3 window controls.

However, the sole reason I'm keeping an eye out for raycast-compatible launchers is the ability to integrate the raindrop.io extension - which seems to be broken when used through Vicinae.

Maybe someone else running raindrop got it to work; "TypeError: Cannot read properties of undefined (reading 'subscribers')".

what version are you running? I'm currently working on improving extension support but yes, some are still in a broken state.
