thanks for your insight! i started to build this project mainly for the tts features but you can certainly just read text on it.
it saves the state of having the narration on or off, so if you ever open the book again you don't hear any voice. also the reading progress and state is automatically saved to your system log files. I'm pretty sure with a few settings in the config.py file you could direct them to your server.
about the monospace fonts. yes, they're not the prettiest but they're very easy to read! easier than many much more beautiful fonts. and if you're tired of reading, just switch on the tts. ;)
In a DE and depending on the terminal emulator, one could probably set up a profile that uses variable-width fonts and switch to it for Lue. That experience would depend on how well it renders text, particularly typographical elements.
that's a really cool idea! i wonder if it would break the ui though? i should try that.
me, mainly i just look for the most beautiful monospace font i can find that has a nostalgic feel. recently my favourite has been "modeseven" (https://online-fonts.com/fonts/modeseven), which is also featured in the screenshot on the github page.
It does break the border, but that's a two-line fix in ui.py to use a Rich Panel without side borders:
Then running lue in an emacs ansi-term or mlterm with a variable-width font configured, it looks like a typical ePub reader.fantastic! good to know.
