I currently use Agenda to track my tickets of shortcut and add reminders i usually insert a few lines of code and they just look weird with the current system, it sould be nice to have a block 100% wide showing the code and with different language support like Notion, shere you put a block and inside of it you can use Python, json, Java, etc…
Other feature that would be pretty neat too is text justification to make it look more organized, idk how hard is to implement this i guess is pretty similar of text coloring in how it should be implemented… i guess since this is markdown is quite hard/impossible? But with a custom self-made stuff it might be possible.
Added an example of Notion
