Why YSK: New apps are springing up everywhere, and if you’re on a tablet, two column views are helpful.
I haven’t come across any other app that does this yet, and while the F-droid version doesn’t seem to have the two column option right now, I think it’ll be added soon, maybe in a few days or so. If you’re interested, you can get the alpha from the GitHub: https://github.com/thunder-app/thunder
Writing this on Memmy; on a tablet. Works great.
