You've nicely configured a lot of services for "share", but I'd like to
suggest that you allow a "Define new". In this option the user gets a dialog
to specify a name, command and options. The options allow inserting the URL,
title, and other elements to be part of the command. For example:
options: %%summary /title %%title
where %%summary is the content of the feed item and %%title is the title.
I know we can write extensions but a lot of useful stuff can be done without
having to go through all the of learning curve.
Yeah I was starting this in 2.1 but was not able to complete, its a valid area
