Hi,
after each upgrade I have to reinstall my plugins for roundcube, because everything is overwritten. But perhaps these plugins are interesting for more people, so perhaps they can be added to the Pluginbundle:
- rememberme:
https://github.com/lefoyer/rememberme
A plugin for autologin, I think I don't have to say anymore 
- filters
https://plugins.roundcube.net/packages/roundcube/filters
A plugin for filtering mails. But it happens client-side. So the filters are triggered when using roundcube. I use this for mails I want to see on my smartphone in my mainfolder, but after using roundcube they have to go to the defined subfolder.
And I found this as a replace for dkimstatus, but I wasn't able to test it yet. Perhaps somebody else?

Regards
Dom
