> Something I am still looking for: folder-based music player with a seek UI that works well for long audio files (for example fine-seeking in a 4 hour long mp3)

I've been using "Smart AudioBook Player" by Alex Software (available via the play store). I particularly like the sleep timer, ability to change playback speed and the fact it seems to cope with extremely long audio files without having any problems.

I use Termux more, but it would be 2nd most used F-Droid app. It's a painless why to make files on your device available to anything with a Web Browser.

I am now super curious how you are using Vimium on a handheld device, do you mind sharing ?

Have you tried Phonograph?

Seems to restrict folder access to "Phonograph Pro".

Vimium on an Android device? Tell me more. What keyboard are you using?

Currently using it with the built-in keyboard of the Unihertz Titan Pocket. Also used it with the regular Titan, the Fxtec Pro1 and the Blackberry Key2. All of these devices have proper hardware keyboards.

On the Vimium side most functionality works the same as on desktop. Tab switching using Vomnibar.activateTabSelection and Vimium's search are the exceptions. You can of course still switch tabs and search the normal Firefox way.

Does VLC not meet your needs for a media player?

Not in case of long audio files.

I have some purchased audiobooks that are as long as 21 hours mp3. VLC sucks at playing those.

Other than this need, VLC is all I need.

For this, I use Voice: https://f-droid.org/en/packages/de.ph1b.audiobook/

Can't find the app. Getting an error.

Did you add any additional repo?

I just checked again and it looks like they have added granular seek buttons for audio-only so it's serviceable now.
