Unless you're thinking of changing how the widgets are listed in skin helper to a hierarchical-by-addon list, that wouldn't work as - unless Library Data Provider, Extended Info & Smart(ish) widgets are installed, skin helper doesn't know what widgets they provide (as at the moment it gets the widget options directly from the widget provider when it caches them.) Split up hierarchically that could work - click on 'Library Data Provider widgets >' and Kodi asks you if you want to install it - but doing it that way would, I suspect, make it harder to skinners to decide how to arrange the various widget providers themselves as they can currently do...

That was indeed what I was thinking... Maybe have both... If you call the skinhelper widgets entry with no params it would show the entries for all addons providing content (which can also be installed on request).
Besides that keep the filter active if skinners want to have control over what widgets to show and what not...

On the other hand the "get more" button is also a nice idea :-)

As this thread is read by many skinners maybe everyone can join the discussion how this should look like ideally ?

option 1: Get a widget listing with all addons providing widgets, such as extendedinfo, librarydata etc. If a user clicks an entry for an addon that isn't installed a question will popup if the addon should be installed.

option 2: In the widget listing of skinshortcuts (the selectdialog), have the "Get more" button displayed. This will result in a popup with available providers to install.

option 3: a combination of 1 and 2 :-)
