If I may, I suggest the addition of a new setting to be applied to the user's .nitrux system: Auto-Action BarWhen enabled, the action bar would automatically toggle on when you have something selected (including but not limited to clicking on a file in a browser, highlighting text, and even typing text. When you no longer have anything selected, the action bar would disappear.
One of the very first things you'll notice is that there's no menu-bars (File, Edit, Tools, etc) and there's no contextual menu (by contextual menu we mean that there's basically no right-click in .nitrux OS). We did away with them, as we see them as redundant items that no longer belong on the modern UX world we live in. But while the contextual menu is not present we make use of something better and easier to access from within your application window, we dubbed this, Action bar (that's the bar on the left).
The Action bar is not always present, it's hidden by default from the user view, think of it as a sidebar which you can toggle on or off depending on the usage, if you want to paste some link you activate it, if you're only browsing through an album you deactivate it. (so instead of getting a contextual menu when you right-click the mouse you get the Action bar).
In it are the actions that would otherwise be located in the right-click contextual menu such as: copy, paste, cut, etc., and also those that would be located in the menu-bars such as: new file, save, print, new tab, so on and so forth. along with any app specific actions. These items are categorized from top to bottom: Common actions, App specific actions and Settings, the order should always be the same.
