In the last months, I didn’t get much time to work on Kate nor KTextEditor. Beside some small bugfixes and cleanups I got nothing commited :/
Guess one of the main issues is, I don’t use the KF5 based version of Kate that much ATM. At home, it is the only editor I use, but I have not much time to hack at home anyway.
Therefore today I installed the same setup on my work machine and will now use the KF5 based Kate for all of my day job, perhaps that motivates me more to take a look at the issues the Qt5/KF5 port still has. (And I will work in a KDE Plasma 5 session with most stuff KF5 based now, including all important stuff like the nice Konsole ;=)
First update: The Get It page got an update to show how to install KF5 based Kate/KWrite from kate.git on openSUSE 13.2 ;) Feel free to send in the needed hints for other distros (to email@example.com).
