Let’s add some more:
i would add Syncthing resp. the Syncthink-Fork android app because it provides a kind of data/device synchronization, which is IMHO much more consequent and privacy friendly than any cloud based solution, including /e/-cloud.
Recently, I found a decent easy-to-use video editor. It is called Joyoshare Video Cutter, which helps me to cut and split any audio & video file without re-encoding, as well as has the ability to merge, convert, crop, rotate, watermark in text and image, subtitle, add visual and sound effects, insert background music, etc. I got it for free due to its just concluded promotion. How so lucky I am.
Incredible os. I’m new, and I’m loving it. Almost everything works very well in my Fairphone 2.
I like /e/ File Manager, Gallery app, Music player, Video player, Mail app, App Store, Weather app, Calendar app, Camera and Note app. But…
Browser: Firefox.
App Store: F-droid and Aurora, too.
Keyboard: Anysoft.
Something else: KDE Connect (I have Ubuntu desktop, and this is a "magic "app…), NewPipe, VLC, Telegram FOSS and Collabora Office.
Does nobody use foobar2000 as music player? If your library is folder based it’s a must. VLC is also not bad.
RpnCalc whenever you need a professional calculator and you have grown up with a HP15C.
TotalCommander as file manager.
Brave as browser.
Ah, and primitive ftpd for file exchange.
I have discovered /e/ Browser can import-export bookmarks, and now is my default browser. Really very good.
/e/ browsers can easily make PDFs. That’s something I enjoy.
I’m enjoying the recommendations so far, lol.
Can you please show me step by step how to export All Open Tabs’ book marks? Please.
Where to find this Open Contacts as apk
It’s available via F-Droid ( OpenContacts - Hide contacts away from apps stealing your contacts information ) but also via the /e/ Apps store.

Trackers - TrackerControl
App Store - Aurora & F-Droid

File manager - File Manager Android 2021 (was ES File Explorer, has a chequered history, but with network connections disabled, all seems fine).
I hope it helps someone.

+1 for KDE Connect it’s a very good app which can sync your phone with your PC on windows, linux and apparently also on Mac.
Then you can manage your phone from your PC.
