Mark instances as favourite

Is your suggested enhancement related to a problem? Please describe.

(User story) As an avid modder, I sometimes have a dozen of instances, whereas I actively play just a few of them. Whenever I open Modrinth App to jump back to the modpack I'm actively exploring right now, it may take me a while to actually find it in my list of instances. This time could've been productively spent on the Forge loading screen.

Describe the solution you'd like

I would appreciate having favourites feature where I can mark an instance as ⭐ favourite, and it would show up at the top of the instances list. Very similar to what Cherished worlds mod offers in the game.

Describe alternatives you've considered

• Categorising all my instances. This unfortunately takes time and is not very intuitive. The categories also seem to always show at the bottom, which is completely different from what I want—for them to show at the top.
