We live again!
Well, looks like I couldn't keep the promise of the last news, but I recently found some time and joy to tinker with subtle again. There are still some things I'd like to change, but never nagged me enough to get my hands dirty again.
Apart from that, there are some uncommited changes like the virtual screen handling code and a bit overhaul of the panel configuration.
I've already added a new hook (client_rename) to make tagging of clients easier: Tagging is mostly based on client WM_NAME / WM_CLASS properties and some clients like Spotify tend to set or change them after the first mapping. Hooks to the rescue: This hook fires, when the WM_NAME property changes and can be used to trigger a re-tagging.
