We have a lot of plugins and without an explanation of it's purpose or personal knowledge of the program,
they are just another plugin ....
Besides SubFolder (folder organisation) and small Description if available,
HomePage link available on most plugins also at Download plugins (so you can check homepage via a Download plugin without downloading The Plugin)
Sometimes Links to "Plugin Page" gives more information where available.
(well mostly people do not have time to create a plugin page, life is fast...)
Sometimes checking history info of plugin may help to find special infos about application or plugin
ex: GSmartControl -> History002=.... link --> see link
rarely there are also info (link to a post or text) available on plugin interface to give specific information about a plugin or application
provides good application working plugins so one do not waste time on implementing or adding features and applications,
and focus on the discovery of applications and features.
That is all we can do on our side
on organizing and distributing plugins.
Still In the end One need to have experience on applications to understand its features before fully using them.
Discovery is fun without wasting time to implement.
In the end,
It is always more encouraging to follow a trusted mentor, anshad, to use applications
Nothing can be better than an advice from a trusted user.
