Bugfixes and little features

Hey! It's been a while but things have been moving. I'm about to finish my master's degree so there were no major changes but I managed to include some small quality of life changes.

For example, posting is now much easier. You can skip the editor and write a short post or upload an image right from the Create Post screen. You can still open the full editor if you want to create something more complex, just like before.

There are some other things here and there but most things are under the hood. As always, let me know if something's missing.
