If Flow should ever get accepted at all I'd propose fundamental style changes:
- First of all the interface wastes by far too much space. Two lines of content are using up approx. five times the space because of
- excessive padding
- the disproportionate header (with user name, edit count etc.) and
- the incredibly large reply button
- Header and reply button should add two additional lines at most. Padding should be reduced to a minimum.
- Secondly the interface does not fit into Wikipedia. We have an Wikipedia interface (or more correctly various skins) with some recognition value. Flow should look exactly like every other page on Wikipedia. That includes especially headings but also all other content:
- Headings should have the same level as on other pages (e.g. "h1" for the page title, "h2" for top level sections (which could actually be threads) and look exactly the same.
- Large green "Reply" buttons or are a no-go. Simple textual links would suffice by far.
- Actually styled buttons should be kicked out completely. We never used them in Wikipedia and it should stay this way. Use native inputs.
Don't start trying to overstyle everything. Stick to the classic skins (and make Flow skinnable as MediaWiki itself) so it blends into the rest of the page.
