A few suggestions around donation data:

Reports: Right now I can see historical donation data (including external donations coming in that I periodically add) and new donations via Stripe which is great. But, it’s still not possible for me to build a report to sum those totals, so I have to manually add them.

Donation source type/External Donation ID: This information, which we upload when doing a bulk upload of external donations, doesn't show up as a field when exporting the donations once more. Where is it stored?

Fields: It would also be helpful to be able to add a field that applies to donations and not to people’s profiles– this would enable us to use a field across historic and current donations that doesn't need to be updated on a person's profile each time a user donates.
