The current biggest limitation in integration is the usage of two different "edit profile" sections: Community Builder and EasyBlog. The biggest drawback is where some of these values show up in various parts of the blog, such as the Blog Description and Short Biography. I would like to see this consolidated to just CB's edit profile via Custom Fields.
An option could be toggled in EasyBlog to auto-fill these values with a CB Custom Field; the admin would have to define the field ID in the backend for this feature to work. Where an ID is not defined, it could optionally automatically disable this field from being displayed anywhere on the website.
Example:
Community Builder Field
Name: cb_easyblog_short_bio; Title: EasyBlog Short Bio; Type: Text Field; [...]; ID: 64
EasyBlog Dashboard Settings
Short biography: (dropdown) ID: 64
