Let me start by saying i love this platform and the read.cash team already :)
in no particular order:
easier way to copy affiliate links on mobiledisplay more than 3 upvoter icons on mobile, there is plenty of space for that
make the upvote/tip arrow blue when i upvoted already, same as for thumbs
make the the dot-sandwich menu button the same style as the all the other buttons (transparent background, instead of the in-my-face grey one)
dark mode
remember my sponsorship data (icon, link, ..) so i dont have to fill it out every time
when i do the paid upvote, do the thumb upvote for me automatically, so i dont have to click a second time
show my seed phrase as a QR code
make it easier to have the same seed on many devices (maybe make it even the only way, so its more fool proof - save the encrypted seed for me)
remember my upvote amount defaults so i dont need to set them each time for a new device
on peoples profile show statistics about how much they earned and spent
button for switching the bullet list to a numbered list
auto-detect language
in the top bar put my name on the same line as the rest of the stuff to save vertical space
on my profile, next to number of subscribers show also the total number of thumbs and views my articles made
@Read.Cash mentions autocomplete in comments
no address reuse
fix link parsing (https://read.cash/@micropresident/a-story-of-how-amaurys-broken-difficulty-adjustment-algorithm-came-to-be-b0b7c142#comment-e1ea7556)
I've seen dark mode there. Is there anyway i can use that too?
