There is a major clean-up of the issues list underway. The things merged should appear when the compiles/binaries get made again. For some reason the auto compile, that was adding new builds to the OTA sites, has been off, I guess, as I haven't seen any new builds since "koreader-kobo-v2015.11-40". The OTA sites only list the "koreader-kobo-arm-linux-gnueabihf-v2015.11-stable", now. I don't know why the others (~10 of them) stopped appearing.
I was getting those OTA builds by just downloading them using my PC. Because they are compressed files that WinRAR recognizes, they open and I can drag&drop the new koreader folder over the old one in the .adds directory of my device. WinRAR or explorer then lets me do a merge replacing all the old with the new. While the device is connect via USB.
Almost all of the user interface is scripted in LUA, and the changes are available in the "merge" at Github. The files effected and the changes to those files are shown; such as
this for the live clock. All you need is a good script editing program like "Notepad++" to make the changes yourself.
Luck;
