PieFed Meta

Do you mean a more compact interface? In your user settings, under your theme selection, you can select how compact you want your UI. There are three levels:

1. Not compact - The default level for new accounts that expands the images/videos for those types of posts
2. More compact - Image posts are just thumbnails (like link posts) and no embedded videos, so all posts take up roughly the same amount of vertical space. <- This one is my favorite
3. Most compact - No images at all, everything is text.

As a curveball, you can try an alternative frontend and see if you can configure it how you like. Photon and/or Blorp might be more your speed, but I am not super familiar with their UI customization options.

There is also !piefed_help@piefed.social - probably !piefed_meta@piefed.social would be more for overall project direction (like "can you add this new feature that I just thought of") and !piefed_help@piefed.social for specific questions, but people are very friendly here:-).

Other commenters already mentioned the Tile and Wide Tile views, but on a related note I wanted to add that you can collapse comments with the pinching-looking icon. All of this is using web interface though, whereas if you are using an app (Voyager, Summit, Blorp, and so on) then you'll need to find the help community for that specific app to find out how to do something in it.
