Is it possible to follow certain Hashtags on the Fediverse (so that you don’t have to remember them and look them up later)?
@Christian
The android app @Tusky supports following hashtags, and also the Mastodon desktop advanced interface lets you pin tags as a separate column.
You can activate the advanced interface by going to Preferences > Appearance > Enable advanced web interface and then click "Save Changes".
