My HA setup is years old now. In the meantime, I have gathered and installed, imported and created many things, including trying to replicate dashboards - which means importing random files in random directories and creating dashboards as pure yaml, etc.
Because of this, through the years I have installed various resources, cards, add-ons, and so on. But now I am at the point where, when I want to add a new card, I get a massive list of cards with previews that slow down the scrolling and it looks all so messy because some cards have different sizes and categories. Then there's also modded cards through custom dashboards, and so on.
I want to clean everything up, but not install a brand new system and add everything back. I thought about running parallel systems, but I read many comments about devices getting confused, etc.
To avoid all that, I want to clean my current system. It's not slow, it's working perfectly, but working on the system itself is exhausting because I made a mess of it. Now I don't even know which layout card is the right one, did I remove the original one when I added the modified one, and stuff like that. I even encountered an "issue" a few days ago, when I deleted custom repositories from HACS before deleting the addons, and now the addons don't even appear on my installed list - and I can't even remember which repositories I deleted.
Is there any reasonable way to do this? Cleaning up the entities is not a problem, but everything else is. I will do it even manually, I just haven't figured out the best way yet.
Thanks!
