Hey George! 🙂
Your question is as follows:
I want to know if I can add a button or a link in the list view of the event calendar.
Ultimately the answer is “Yes”, but doing so requires custom code which we are unfortunately not able to help with here on the forums 🙁
Editing code like this just to add a link can be done using the methods outlined in our Themer’s Guide here → https://theeventscalendar.com/knowledgebase/themers-guide/
I’d recommend checking that out to get an idea of the process.
As for the general question about whether Avada is a good theme for our plugin: I don’t use Avada and haven’t used it myself, and my personal tastes push me towards other themes, but I do know that Avada’s developers are nice people; responsive in terms of support and such; and that many, many people use The Events Calendar with Avada and love the combination.
I hope this all helps!
