First: I really like Manager. As a starting business it fits my needs perfectly. Awesome development pace!
On thing that is not a problem yet but surely will be in the near future is the listing of things like Sales invoices, bank statements, and such things.
Pagination on those lists is no luxury, I’m quite surprised no one has asked for it yet.
A bit nicer would be filtering: keyword filter, date from and to (preferably with a date picker), that sort of thing.
We talked about this before, but I think it’s a good forum topic, also to see what others think.
