Hi Natassia,
Thanks so much for reaching out and for your interest in our products!
1. Do you have an option for adding a suggested donation ?
We unfortunately do not have that option, but you may be able to integrate a third-party plugin in order to achieve that functionality.
2. Can this plug-in do Pay-What-You-Can?
No, we do not have this option available out of the box.
If this functionality is a requirement for your intended project, I’d suggest that a third-party developer would be the best way to make this feature happen on a short timeline. ? We maintain a list of developers who work with our plugins on our Knowledgebase here:

Is there a limit to how many custom fields you can populate?
No, there is no limit on how many custom fields you can create for your tickets!
Is there a limit to how many events with tickets we can have live at any given time?
No, there is no limit to how many events with tickets you can have at once. The only consideration would be performance on your site, but there are many ways to optimize performance with your events, especially if your host can handle the traffic that your site will get.
Let me know if you have any other questions!
Thanks,
Jaime
