Feature Request Description

Some plugins must finish their background work before start them again. In cases: update, reload.

I suggest adding deferral parameter in OnDismount method that will give plugins fixed time like 1 second to stop their background job before Decky will run them again.

better option is to make onDismount async (if it isn't already?) and await it

I agree. It seems that it's not the default behaviour right now from a quick glance.

The Decky simple calls:

decky-loader/frontend/src/plugin-loader.tsx

Line 216 in b84dcd9

plugin.onDismount?.();

decky-loader/frontend/src/plugin.ts

Line 6 in b84dcd9

onDismount?(): void;
