To add to this, it would be great to hide complete sections or overwrite content of a specific section as if it were a template. Since the Donor Dashboard is a shortcode I thought it was editable like this but it does not seem to be: https://givewp.com/documentation/developers/customizing-give-shortcode-templates/

I forgot to mention that I also need to edit the email (subject line and body) that is sent to confirm the donor's email address.

Yes it's essential to have hooks and filters for everything, and it shouldn't be difficult at all to add them. I need to change some language and remove some elements (like others here have commented), as well as add links to our latest financial reports, Guidestar page, etc. Hooks and filters everywhere please!

It would be very helpful to be able to hide the 'Edit profile' tab as this doesn't update records in our main CRM. Pretty frustrating for donors if they think they've updated their records with us but haven't.

Yes please! I'd really like to hide the Anonymous Giving block (it has no relevance for our configuration and is just confusing for donors), and would appreciate specific classes for all elements for full control and customizations.

I too would like to customize some elements of the Give pages more.

I vote on more specific classes for all elements. It would help customize the dashboard. Currently, all buttons, headings, inputs have the same classes so it's very hard to adjust styles for specific elements.
