i am new in linux and wondering if there is a way to install plank on kde plasma
Well, lxqt uses it, it works such as it is in unstable. However - they fixed it, it is back in testing after being taken out. I found 0.10 much easier to edit. I installed dconf-editor and all it's dependencies to make changes that editing in nano used to work. Mostly worked on by Ubuntu so locating bug reports best at launchpad
/net/launchpad/enabled . . . sigh of remorse
Hey, go install and kick the tires.

irc on freenode #plank
edit: but do you really want to add GTK3 to your QT5/KDE Note: it does not clash on QT5 LXQT
