@dostovel Hi Omar, a few hints:
If you go to Edit > Preferences > Keymap > Preferences > Select All Toggles, you can use select/deselect all with ‘A’ again. Otherwise it’s ‘A’ to select all and Alt ‘A’ to deselect all (actually quite handy).
To get rid of Gizmos: on the top right side of the Viewport there is this icon that looks like a bow and arrow, this is not to wake up Robin Hood, but to turn on or off different Gizmos!
For setting the Origin there is unfortunately no Shortcut, you’ll have to go to Object > Set Origin >…
You can get the dots in Face Mode back by going to the ‘Yin Yang Circles’ (right next to the ‘Robin Hood’ icon), this is the Overlays menu. Open it (when in Edit mode!) and under Mesh Edit Mode tick Center.
That black menu on the lower left that keeps popping up is highly annoying I think; somtimes it covers the part of the model I am working on;) It’s a bit like the former F6, but without me asking for it.
Have fun exploring 2.80 further!
