3 columned profile page

### Problem I have

When I go to a profile's posts, I only get one column and two buttons:

https://phanpy.social/#/en.osm.town/a/109396801590808443

By default, this shows posts and boosts. One button lets us remove boosts, the other one to add (to the default) replies. So the options are posts + boosts (default); posts; or posts, boosts and replies. This leaves out all the other 4 useful combinations: boosts alone; replies alone; posts and replies; and boosts and replies (ok, maybe not that useful).

Granted, posts and replies can be obtained by manually fiddling with the url:

https://phanpy.social/#/en.osm.town/a/109396801590808443?boosts=0&replies=1

### Solution I'd like

One possible solution is to have posts, replies and boosts in 3 separate columns. Granted, this should only be possible in wide screen formats (so, not on mobile, _maybe_ in landscape tablets?).

### Alternatives considered

Instead of the current 2 toggle buttons, 3 toggle buttons for filtering: posts, boosts and replies, and turning one on allows those kind of posts to be seen in the single column. This could work for small screen formats. The default could stay as it is, with the posts and boosts buttons toggled on, and replies turned off.
