Last night while I was searching for alternative window managers I discovered this wonderful GNOME Shell theme called "Paper". After installing it, I'm enjoying looking at my computer screen.
Here're some screenshots.
|Applications Overview. Look at the menu menu on the top right.|
|Nautilus with folder icons|
|Tweak tool showing the wonderful checkboxes and the settings I had to change to achieve the theme|
Another useful app I installed is Synapse launcher. Ctrl+Space and it gives me access to everything I need.
With these, somehow, I feel like my computer has gained a few milliseconds in speed.
