kdevelop Huh, yet another KDE app. Installed now. Seems to be just as suitable for my needs as Kate even though it says to be centered around C/C++. Unlike Kate it has something called LSP which might help with automatically adding closing tags; but I have yet to figure out how to activate this. VS Code/Codium seems to be omnipresent when diving into the topic, but I just don’t like that it’s controlled by MS, even if these are opensource.
