What I want to do:
Use my favourite plugins.
Problem:
I can’t save any plugins, neither on my organisation or private account.
Some plugins does not appear as recently used.
I have to search and remember the name for all plugins I want to use every time.
Suggested solution:
Make it possible to save plugins that I personally want to use.
Or have I missed some setting that I need to change?
You missed the save plugins feature.
Please see the following Help Center articles:
I read this like five times until I understood where the [•••] could be found.
I realised I was not supposed to press “Run” and therefore missed that I could look at the plugin itself. 
My suggestion is to add a shortcut or a save action without the need to view the plugin info.
Thanks for the help. 
I miss this either! Why hide the save button in [···] ?
Where is the […] button? I can’t find it anywhere?
I made a short gif to show you where to find the save feature. 
you are a goddamn hero my friend! thank you
