My 2 cents: I am really grateful that people are thinking about how to improve Gnome, but I have to admit that I don’t like this proposal. In my opinion, Gnome is almost perfect in its elegance and simplicity.
First of all, I dont understand why there is at all the need to know and thus have it indicated in top bar on which workspace I am. I mean, it doesn’t really matter. I don’t have in mind which app is on which workspace, and why should I? It is not necessary for switching to an specific app to know on which workspace it is situated. Very rarely I switch to another app by switching the workspace via keyboard shortcut or in overview. In general alt-tab, hitting super and entering first letters of app name and press enter or clicking on app icon in dash in overview does the job. Well, that is not quite true. Quite frequently I open the overview and scroll through workspaces to get an orientation. This has also the advantages of the possibility to rearrange the windows or to switch to one. In the past, I had experimented with extensions like workspace indicator or improved workspace indicator, but I always ended disabeling them. They dont give me any value, and if I really need to know on which workspace I am, Overview will tell me. These indicators as well as this proposal are further quite annoying when overview is open. If you cycle through workspaces in Overview, you then have 2 places that indicate the same workspace switch. The indicator under the search bar, and your new indicator. That is redundant and annoying.
Though I have to admit that I am missing for long time the possibility to switch workspaces with mouse only without opening overview. (existing extensions for that often conflict with volume control or other things) In my view, it would be desirable to be able to switch workspaces in normal mode (that to say without the need to open overview) by scrolling mousewheel if cursor is above date/clock or above Activities button in top bar.
I should mention that the only extension I really heavily rely on is hotedge. It gives you a quick and easy access to overview by moving mouse cursor (similar to functional corner) to bottom of screen (where you need it to switch/start app via dash). Hotedge should be implemented in Gnome by default.
Further I have noticed that your proposal also hides (now I dont have the right vocabulary) this field with the name of the app of the currently activ window next to the Activities button. |attachment
This field should stay where it is since it often is the only way to know what the activ app is and what is its name. Further you can do stuff by clicking on it like closing app or open a new instance.
And here comes my second propsal what I would change to make Gnome perfect if I had the ability to do so: This field gives you the same context menu for left and right mouse click. I would keep showing context menu for right klick, since it is kind of a standard thing that right click opens context menu and would enable cycling through open instances of same program by leftclick so that it is possible to cycle through instances of same program with mouse only without the need of keyboard shortcut or opening overview. If there already is an extension that does exactly this, please tell me.
To the design of your indicator, I have to say that the long sausage, as others have referred to it, is really quite annoying. It does not help to quickly understand on which worksapce I am, it rather forces me to do a calculation: I see 2 dots plus the sausage, so I must be on workspace 3. That is weird And as others have mentioned, there is a inconsistency of the scroll direction. In overview, you scroll down for moving one workspave right and up for one left, as it should be, and your indicator does it the other way round.
Hope my remarks are helpful.
