I looked for a setting for that as well. The “see more” is a nice way of keeping the calendar display symmetrical (and not distorted, top to bottom). However, for a calendar that has limited entries for any one day (e.g. bookings of a single-use-at-a-time facility), it would be a great alternative to have (controlled by a setting/parameter).
Hey @jorgerp and @johngoold-1!
Thanks for posting your questions!
You can disable See More button by enlarging the value of Number of displayed events setting. It can be found in the theme options, which you are using on your calendar.
I am attaching a screenshot, where you guys can see the setting.
Cheers!

Many thanks for the answer.
Changing that parameter is only possible in the paid version, am I right?
Hello @jorgerp!
That’s correct, unfortunately this setting is only available in Pro version of Spider Calendar plugin.
Cheers!
