Agreed these would be the most sought after enhancements from my point of view although just being able to specify the WiFi channel manually for both 5ghz and 2.4ghz would be the most welcome, my M5s runnin firmware 1.4.4, had a tendancy to select the most congested channels! But I finally got the to auto swap by rebooting all the nodes via the web interface here http://tplinkdeco.net/webpages/index.html and going to advanced / system / reboot!

Doing reboots via the android does not have the same effect as it's impossible to reboot the primary node!
