Update to the README: What is the difference between the three applets provided by this project?

[hugobuddel]

This project provides three applets, with this description in their about:

• Indicator Applet
• Indicator Applet Complete
• Indicator Applet Application Menu

However, the I could not figure out what these three exactly do and when to use which one. They all have "An applet to hold all of the system indicators." in their about. Maybe we can put a short description about them in the README?

I'm willing to create a pull request for this, if someone can give me a pointer some more information about these applets. Would such a documentation improvement PR be appreciated?

This is my interpretation:

• Indicator Applet shows all Ayatana Indicators, except for datetime (and appmenu)?
• Indicator Applet Complete shows the same thing as the Indicator Applet plus the datetime indicator? Or are there more differences?
• Indicator Applet Application Menu only shows the appmenu? It always shows "No Indicators" for me. This seems to allow the application menu to end up on the panel, like is common on MacOS, is that right?

The README in this repository is the place where people end up when they google for the name of the applet, so maybe we can add some more information for those visitors. E.g.

• A link to more information (if there is an existing description elsewhere).
• Guidelines on which applet to use. E.g. why would someone use Indicator Applet Complete over Indicator Applet?
• Some information about how to use them. E.g. how to use the appmenu indicator?
• How to configure the indicators. E.g. how to add the date to the clock.

I can write a draft for this, if that is appreciated. I don't actually have all this information myself, which is why I came here, so it will be limited.

As an extra, which kinda goes beyond the scope of this issue, it would be nice to get a sense of the planned direction of the project. E.g. several things that are unclear to me, and would be nice to be able to learn from the documentation:

• The power cogwheel to lock the screen etc does not indicate anything. So should it, at some point, be removed from the applets, or will there be more non-indicating indicators, or is the cogwheel the exception?
• Will 'redundant' applets (like the clock) be deprecated at some point? (The fast-user-switch-applet seems to have met that fate.)

Perhaps there could be a 'Help' item in the context menu with the above information?

Most other applets have a Help (Clock, Notification Area Applet, Lock Screen, Log Out Button, Workspaces, Show Desktop, Window List), only the Indicator Applets and Menu do not have one. This would be beyond my skill level though.
