I recently did a dist-upgrade on my Debian Sid, for the first time in about six months. I now have KDE 3.5.1 - Kate 2.5.1 v. KDE 3.4.3 - Kate 2.4.1 previously.
The Kate 2.4.1 terminal (Konsole) window had a close box, an empty box and a box with a diagonal arrow (to undock the window?) in the upper right hand corner. My new version doesn't have these boxes.
I have read the help manual and googled the web but have not found anything referring to this feature.
Is this feature not availablle in Kate 2.5.1 or am I just too stupid to figure out how to enable it?
Nope, these bars are gone and there's no way to configure this (as far as I could see). There are a few options when you rightclick such a button in the sidebar, but I wonder if that's sufficient for you.
No, there is no way to get the old behavior back.
You can bind a shortcut to "Show Terminal" btw, it automatically toggles then and should have the focus set in the right way.
