I've made a note of it before:
Some gnome/adwaita based apps have their own built in window dressing which sort of "doubles" with the Elive theming.
To keep the Elive experience a bit more coherent we should try not to use those apps i.e find replacements.
'gnome-taskmanger' is one of those apps and while awaiting a finished EFL version we should consider using 'xfce4-taskmanager' or 'lxtask'.
Personally I think 'lxtask' is the nicer of the 2. It has a nice minimal, no-nonsense look to it.....here's a comparison:
- On top is xfce4-taskmanager and lxtask is below.
I prefer xfce4-taskmanager because of the graph feature (and I think it has more features)
Actually we have these replacements available, hit your new full-featured launcher and type "evisum", you will see it has 3 modes (same command, 3 window types)
So now (and in the future) the question will be more like: "is there any reason to not use evisum? because, EFL is the preference, but the application can be buggy, lacking features, not-intuitive, etc... there's nothing wrong using gtk (or other) alternatives but is just a matter of good vs bad points
So, what' you think about evisum compared to these ones?
