There seems a lot of room for UI/UX improvement in Phabricator, just look at these long width fields.
Recently, I became very confident using Vuetify to produce one-screen interfaces: you can imagine form that fits the screen and has everything needed. Another major change would be to utilize markdown-it for rendering content (wiki, maniphest tasks, etc.; also look at advantages brought with its extensions, including interactive elements), preserving all Remarkup content links recognition (perhaps make separate components for these, so one can customize them with the power of Vue+Vuetify).
But I wonder whether it will get support at least from community. So since it’s the single place I can really ask and get response, I want your opinion, folks.
