A clear and concise description of what the problem is. Ex. I'm always frustrated when [...]

I'm always frustrated when: My features disappear each time I do an update, and then remember that after every single update I have to go back and manually re-enable pretty much all of my previously enabled apps.

Describe the solution you'd like

For the updater to automatically re-enable them when done updating. Or if concerned about 1 or more apps potentially breaking the instance after re-enabling, allow adding a flag to the update command(s)/Update UI to optionally re-enable after, with a warning mentioning potential breakage. Perhaps even add this option as a setting where users can toggle it on/off.

The logs should show which app(s) break the instance if it were to happen.

Describe alternatives you've considered

There are no alternatives.

Wrong repository? This doesn't have anything to do with Viewer? :)
