I have a few ideas which are mostly related to getting a bit more data about Patrons. (This sounds evil, I know!
)
This matters to me because I am running a Forum/Website just for my Patrons and manually manage their accounts - safer that way, since there are still bot accounts pledging for me several times a month.
So I’d love to get a bit more insight into who is who. Two things:
1: Identifying Patrons Properly
Say a new Patron pledges to your project and he’s currently named “John Doe”. And uses a specific email address.
You wrote him into your list, he made an account, he got his gooddies… And then he decided to change his username, as well as his email he uses for Patreon. Then he changed his pledge level ontop of that.
As of now, at this point the Patron is no longer identifiable.
As an improvised solution, I will then search through my archived emails trying to look for notifications sent by Patreon - and then I have to manually click the “View Profile” link in every email, hoping to be lucky and land on a profile with a new name.
This is very, very time consuming and often does not lead to any success
.
So here’s a suggestion:
Show the numerical user ID in the Patron manager. So that Patrons can always be found by their account number, independently of their username or email address. This would also make the .csv list export TONS more useful, as records can be painlessly linked! Should be a minor change, too, since you already have that data. 
If this is a no-go, alternatively you could do the same thing that services like Steam do – show a list of past usernames.
So that there is a track-record. John Doe - Also known as: GrandMaster999, OtherUsername, YetAnother Username
2: Patron Track-Record
A second feature request is to bring some sort of indicator back that quickly lets a Creator see the good deeds a Patron has already done - in total, not just for the own project, which is still being shown.
On the old profiles, this used to be the case. There was that circle icon
, as well as a numerical summary of the total pledge contributions in the past.
On the stylish new profiles, that information is sadly gone.
It is vital to know this because there are (some) Patrons who are either bots, or extremely unreliable (by accident, or on purpose).
This mostly affects Creators who do not use a monthly pledge cycle (such as myself), since then, new Patrons aren’t charged in advance, and thus have a lot more leeway to use fake credentials, at least until they’re flagged as fraud in the next month. 
So a suggestion for this might be to add a badge feature to profiles (again) that indicates an account in good standing, and with a positive pledge history.
Or tweak the “Status” column that already exists in the Patron Manager. Instead of just saying “OK”, it could be saying “OK - Good track record
” for Patrons with 3 months of being awesome, and for those who have run into pledge problems with one or more Creators in the past 3 months, it may say “OK - Mixed track record
”. Those who are new to the site may have “OK - New On Patreon
”.
I know this only affects less than 10% of all Patrons, and most people are reliable and honest, just it would really help to get a little bit more insight into the data that you already have about peeps, especially since this was possible in the past.
