Reindex button at manga/anime sections

[joex92]

Describe your suggested feature

Add a button, or option in the 3-dot menu, at the anime and manga sections as a shortcut to the Reindex downloads button in settings.

Other details

Lately it's been a pain that sometimes the downloaded content is not shown and I have to go to more -> settings -> advanced -> reindex downloads then back, back, back, back and check that is working, because rarely it doesn't work, last time i had to restart the phone because the reindex got stuck...
