It's my go to app for reading text files. You can set letter size, spacing, color, font as you like, so it's easy on the eyes :) Highly recommend! The only problem I had was that earlier bookmarks keep disappearing once you get to the later part of the txt file. Or the bookmarks seem to be resetting when you open the file the next day or something :(

The bookmark seems to be malfunctioning. Try deleting and reinstalling the settings after backup. For a backup, click the app icon at the top of the file list.

A good app for epub and txt files, but I wouldn't use it for pdf viewing. I haven't explored all the features but it performs well for reading and you can edit the text (works better for txt files). Limited selection of fonts but you can add your own so that's fair. Interface is simple so it doesn't take up a lot of storage .

I really want to see a zoom bubble so I can just hold down finger and zoom to see text that is a bit difficult to read. The app has been improving but can we please get a real zoom when using toon reading mode?

You can zoom in using two fingers and keep ratio in "Settings-Image Viewer-Etc Option", root access in SMB is not support yet. You can not zoom in webtoon mode at the moment.
