[Feature] Grouping/hiding instances based on filters/folders

[justeraseme]

I do not need to see all instances at once. I should be able to hide all instances except specific ones at one time.

Possible implementation ideas:

• A simple search bar (not really fancy but better than nothing)
• Clickable folders (click an instance entry to open a "subfolder" with instances in it)
• Pinning instances but hiding all others? / General pinning system (as seen on the Discord suggestions)
• Groups (???)

Some design proposals also exist on the Discord Server: https://discord.com/channels/1280474064540012619/1292374160575692852/1407337292317724795

Checked the discord and it also exists under "Pinned Instances / Sort Instances" in #suggestions but I'll keep this issue here for tracking purposes.

Thanks for the suggestion! Will work on this when I get time
