Hello,
That is quite the amounts of Venue’s and Organizers you have there. You are correct there is a 200 limit set for those.
You could change the limits yourself. This would be overwritten on updates, but could help you today. There are not filters to change this without modifying the plugin either.
Here are the two files.
\the-events-calendar-filterbar\lib\filters\TribeEventsFilter_Venue.php
\the-events-calendar-filterbar\lib\filters\TribeEventsFilter_Organizer.php
Is there any way to switch those dropdowns to some kind of AJAX-powered autocomplete instead of the list as itโs generated now?
That is possible, but not without customization or us adding it as a feature.
Please head to our UserVoice Page and add your own feature for this as they will increase the chances of it being added to a future version.

Let me know if you have any more questions.
Thanks
