Feature Request : Content filters

This is a feature that I loved and used a lot on Tweetdeck, but I couldn't find any Mastodon client with the same thing so far : adding filters to columns/shortcuts.

Here is an example I found on Google Images for reference :

I'm especially interested in keeping only tweets with images/media for a given column.

Please let me know if you need more details :)

No files, tests, or entry points are named in the issue. Start by locating how columns and shortcuts are represented, then define the filter behavior, including the media-only case; done should include the requested filters working for a column.
