Segment support

Thank you for this great plugin, I love its simplicity and the sleek interface!

However, there is a feature which I would really love and nobody else has it: the possibility to apply a GA segment based on the user.

For example, I would like a certain user role to only see data with the X segment applied.

This would be hugely helpful for multisite installation where often all sites are in the same GA property and you have a segment for each one. In this way, each WP user would see only the data for his/her website.

Thank you,
Guido
