I use sync occasionally, and I found it has some features literally no other app has (or I’m too dumb to find them) like easy instance switching. It’s right there on the main screen, you just click instances, pick a federated instance, and boom, now you’re seeing stuff from that instance. I wish more apps has that.

My Kobo Libra Color does it. I do sometimes need a bit of time to format manga properly but it’s perfectly doable.

I’m still on my Zen1 1600, with DDR4 RAM and RX580 8GB which I built back in 2018. Whenever I’m thinking of upgrading I just look at the prices. I’d basically need to upgrade everything, maybe aside from GPU which would become a giant bottleneck, so it should be upgraded as well.
I really don’t even want to think about gutting my PC and upgrading, I’d much rather switch to a console.
