there seems no central place here to talk about, or list open-source plugins.
( Forgive me if I’ve missed something (I have looked hard).
Taking the example of the open-source Redmine project: they do a good job of allowing people to publicise their open source plugins, in a directory
See the link to the Plugin Directory from this Redmine page:
Having a central place where plugins can be shared and improved together: would perhaps help accelerate SuiteCRM take up.
Right now, I see on Github that good plugins are being produced in the community: so we just lack a Directory for them here.
eg
gluu-sso-SuiteCRM-module
https://github.com/GluuFederation/gluu-sso-SuiteCRM-module
PS - for quality, paid-for plugins SalesAgility have partnered with sugarforge at store.suitecrm.com which is an excellent resource.
But that still leaves a gap for the community-coded plugins.
(actually store.suitecrm.com is not perfect - as searching there fails to find the excellent plugins that SalesAgility provide elsewhere -eg the OutLook one! sourceForge ought to add those plugins -to stop confusion when people search and not find them
