mobile support
While desktop & markdown is great for creating cards, I often tend to review them on mobile, since it allows you to use waiting times more productively.
I realize proper mobile support with a separate app might be out of scope for a free one-man-project, but I just wanted to put it out here just in case it's not.
From what I can tell from issue #14, it's possible to use a terminal on the phone and ssh-ing to the desktop machine where hashcards is installed? Some documentation on how to make hashcards work on mobile might be useful.
For android users termux is an option, it builds there.
Perhaps serving the html ui over the network and accessing it on mobile phone can already be considered mobile-ready?
(yes, you might need tailscale running or something, though)
I believe my feature request to have hashcards as a self-hosted web app (#77) could serve this use case. You'd need a server to host it on, but if the web UI was set up as a PWA, you could visit the page in Safari (on iOS) or Chrome/Firefox (on Android) and "Add to Home Screen" / "Install App"; it would appear as and behave like a native app, and the developer(s) wouldn't have to fuss with getting it into the App Store / Play Store.
