Absolutely, man. I'm definitely not a fan of the web interface and do 97 percent of all browsing with the apollo app on my phone. The website is kind of weird and my screenreader focus seems to bounce around a lot and it is annoying.
Having a desktop app would be great and pretty convenient for me, and I'd actually planned on writing one myself once I learned enough python.
I sort of envisioned a TW Blue-like layout, a treeview with your home feed at the top and all the subs you're subscribed to underneath. I kind of imagined a list of posts which would have the usual save, upvote/downvote, reply, etc as things you could tab to and to view the post and its comments I thought about another treeview with expandable and collapsable levels, because sometimes I like reading top level comments only and hate having to sift through 500 replies.
Those were just my notes I wrote down when I thought of doing this, but that would be my idea of a great desktop client... for windows, at least. Even if it looks nothing like that, I'd still take anything you got. Rock on, bro.
