In Lazarus I sought to have this enabled. What I exactly mean (just in case it is unclear) is that usually if I <Alt+Tab> from a non-Lazarus program to Lazarus, only a particular Lazarus window is focused on and it may the one that I actually did not want focused on immediately. What I tried is to find an option that would allow all Lazarus windows to be treated as one unit. So if I <Alt+Tab> to it, all Lazarus windows show up, and to make it even better to have it in such a way that the source editor is immediately active and ready to be typed to.
I could not find this option nor did I find any forum thread about it. Any relevant help is desired and appreciated.
EDIT: if it matters, then I additionally write that I'm using Lazarus under Linux.
