Thank you so much! Another person, @elsewhere0789, suggested the same in private. I've installed koreader on Android but it is not much user friendly. But I'm looking forward to buy a #Kobo#ereader install #postmarketOS on it and install this #koreader on it.
But that would be about a year from now as I'm having too many technical debts
I'm thinking, a very basic #WM written in #rust which loads koreader and a #gemini browser.
