Updating addons

Hi,

I was wondering if there is a way of knowing which addons are linked to a repo and which arent? That way I`d know which addons are not autoupdating and only keep track of those.....

Also, generally, when updating an addon manually, is it recommended to uninstall the previous version (and lose stuff like favourites etc) or is it ok to just install the new version over the old one?

Thanks!

Normally is should be fine to install over the top, but if you have problems, that's the first thing I'd redo
