Where in e16 can I manage desktop widgets

  1. There are options to manipulate those using the key-combo 'Ctlr+Alt+right-mouse-click' or, in case of windows the little blue square top-left allows the same options.

  2. For a tad advanced users who don't mind some command-line magic, there's the 'eesh' shell specifically for e16.
    Do a 'eesh help all' to see what's available.

  3. Then there's the menu: 'Enlightenment' -> 'Desktop' and 'Settings' where inside the latter there are options under the 'Desks' and 'Areas' buttons.

There's a tutorial on customizing E16 here with a section on the pager here:
