Thanks a bunch for all of your replies and sorry for not reviving this thread earlier.
So, let's get going:
@nikgnomic sweet, am in the process of getting used to XFCE via AntergOS yet I still like MATE better / thanks for the evangelisation.
@lah7 I am guessing that Caja is a standalone group and not UM related? Furthermore, not only is this not windoze, we never want it be it however even windoze has possibly 2 (or 3?) good features I think. Also, I feel ALT+F4 is more of a habit related to "close" than CTRL+ALT+DEL bering related to the Task Manager. We are just getting holistic however now
@Bill_MI I believe you are my kinda guy! First, I would like to state the fact that my post was simply about making this whole experience better. In no way, shape or form, I am/was blinded by it's pluses and raison d'être. After all, I have been a commercial Patreon for over 2 years now. Either way, I appreciate your feedback and, my bottom line would be, that my initial reason for posting this is because I too try to use the mouse as lesser as possibly can and rely on keyboard shortcuts as much as I can possibly can. Having switching my entire eco-system to UM now, I would surely like to be able to reinstate all of those l33t keyboard habits that I used to be using back in ... 2008 (and 1998 for that matter).
Best regards and do not hesitate to keep those feedbacks coming for DEVs to build their roadmap around our thoughts and experiences ;D
