[All Plugins] Easy access to old plugin versions

[Palloxin]

Describe your suggested feature

To revert bad updates. Bad one might include these : (cases where the update goes from broken => working are NOT included)

1. a working plugin coverts to pagination, and as of the date of this post, pagination of the app sucks, a lot
2. fickle devs that push a flawed (worsening) update and gets merged, and the said fickle devs dont bother to come back and fix it, because the flaw may be discovered too late cuz few users use it. Yes it happens.

Other details

Tachiyomi way has "apks" for extensions, and it's easy to to fish back old versions, but on LNreader it's quite a bother to bring an old version back.
