Here's what my new Akkomane (a.k.a., Akkoma + Mangane) server looks like.
I'm quite pleased with the results. Both desktop and mobile views look tremendous. The default colours are so good, I'm not changing them.
The compose box is elegant and has wonderful options, including scheduled posts. I can also do quoted boosts (a.k.a. quoted retweets) if I want.
I really have to express my appreciation to @reiver and @spacehost for making this happen. I know they put a lot of hours into making Akkomane an option, and it's paying off handsomely.
