* Librera Pro, a featureful, reliable reader for ebooks of many formats, pdfs &c.
* Chroma Doze, configurable white noise
* Privacy Browser, lets me turn off both images and javascript, and seems faster sometimes, especially for quick/frequent lookups from bookmarks.
* IceCatMobile, browser for other sites I leave open for later ongoing reading.
* Handy News Reader, great RSS news reader once I got used to it; now my favorite by far.
* NewsBlur, works well for me for a few particular RSS feeds
* RadioDroid, fabulously wide selection of internet radio in a very convenient app
* AnkiDroid, extremely useful to learn things ~ permanently
* Wikipedia
* VLC
* Senreta Vortaro, esperanto/english dictionary
* DroidLife, somewhat interesting Conway's Game of Life app
* OpenFlood, a curious little game, and way to keep from pocket dialing w/o turning my phone off manually (I had an on/off switch fail)
* NightScreen, blue light off before bed, but have to turn the schedule feature auto off then back on each time after rebooting, it seems (at least on my phone). Worth it to me.
* CPU Stats -- but I *really* wish for something that said *what* was using the most cpu, like top. Maybe just top, after rooting my next phone.
* send with FTP and ghost commander, to move files from phone to computer quickly
I wish Gospel Library (content from my church) were on f-droid, then maybe I wouldn't use the Play store at all. They do let people download the code and submit patches, I believe, but I haven't got into details so far.
While these are very useful, I don't trust the stack enough to use my phone for any confidential things like passwords, banking or ssh yet.
Does Librera Pro support notes and highlights? I can only find a very prosaic bookmarking feature.
Do you have other suggestions for ebook readers with notes support. I really like KOReader (the e-reader app), but it has an annoying display bug on my pinholed fullscreen device.
Good question. I only noticed that if I go to the bookmark list, and tap/hold on one of them, it brings up a small dialog where I can enter more text in its name. I don't know of a way to make it obvious while reading that there is a bookmark at that point, but I'm no expert, and haven't really explored the other e-book readers.
The f-droid.org app (and probably web site) refer to https://librera.mobi which might have more info in the FAQ, and there is apparently a link to the author's email (at least in f-droid) who might accept $ for support or added features for all I know (or similar for other app authors) :)
After this thread dies, you're welcome to contact me if there is something else I can attempt answering, via my profile url.
