WP Google Calendar Manager – Google Calendar Plugin

I wanted to love this, I really did. I even purchased the pro version. There are a couple of issues that kill it for me.

Responsiveness: Essentially unreadable on a small screen, shows 3 characters of the event title.
Event Titles don't wordwrap at all. So half the title may be missing, and they aren't shown in the hover tooltip either.


Fixing these two things would make it almost a perfect plugin, but since mobile responsiveness is a must have, I had to rate it down. If these are fixed, I'd love to rate it a perfect 5 stars.
--Edit: I was able to fix all but an issue with line breaks in the tooltip myself, but now am running into where synced events display on sync, but then don't seem to save. Also, having an issue showing multiple calendars on the same page.
--Edit 2: Updated Review. After purchasing Premium, I was contacted by the authors and told to revert to the unmodified version (fair enough). Once I'd done so, they said I'd need to go into their support queue, and they'd get back to me. Five days later, not a peep. I was able to write my own plugin in that time, and did. Not really thrilled with the support here, although the idea was sound.



Disappointed - Poor Support, Not Mobile Friendly
