Thanks for the feedback @manuvmusic and making updates all the time to this addon so please keep an eye here for updates:
Let me run through your points.
G1) That was added in the cache as some people would refresh their browser so it kept as much data as possible to stop having to type it in again
G2) Good idea but difficult as the way the pages export it’s different every time so you need to follow the steps in the manual to create the button (as you found it)
G3) Good idea and have this already in a BETA version but requires setup on the Google accounts side. So might open a support headache so still thinking how best to do this.
F1-4) Thanks for those and will add more fields in a future update
F5) The auto greying without a database is difficult, one work around is relating to the Google Sheets integration and showing a Google Calendar.
E1) I think that’s something on that server as you’ve discussed with Doug. It should use PHP mail on the server to send it out. Gmail or yahoo should work fine. If it’s not working, please ask the host for their input and send me a DM with server access and I’ll have a test.
E2) Yes we had this but took it away as it was getting long on some emails and some users didn’t like it. Maybe bring it back as an option is a good idea.
