first of all, sorry for my english, that is not perfect

I am new to this forum, because i was planning to buy VueMinder Calendar. Right now i am testing the trial pro version (8.3.1). I am sorry to say, that i found some bugs, that prevented me from getting the full version.
The calendar could be the best one on the market, if you could fix these bugs. The sync with Google is absolutely important for me, because i manage all my events with Google and i want to be able to have access from my computer (client VueMinder) and from my android device (Samsung Galaxy S2).
Here the bugs, that i found:
1. Sync from Google --> VueMinder:
- Automatic does not work, i have always to sync a second time manually to see the changed or new events
- Reminder is not synced correct. I selected "0 minutes before event" in Google, but VueMinder shows always 15 mins.
2. Sync VueMinder --> Google
- After first syn, the event is shown in Google, BUT no reminder at all
- after the second manually sync the reminder is also shown in Google
3. The event list is not refreshed all the time correctly
No bug, but an idea for improvement:
- Possibility to group the events in the event list by start DAY only and not by day and time
(i would prefer one group per day, even if i have many events with different start time)
- Label the groups for today and tomorrow not by date/time, but by "Today" or "Tomorrow"
I hope, you can fix this soon, so i will be a new customer
