Sorry if anything is not formatted correctly; this is actually my first post here.

I use a password manager (keepass 2), and one of the ways it enters passwords is to make partial use of the computer's clipboard, in combination with keyboard inputs. Problem is, it seems Klipper likes to save history. So small snippets of my username/password are shown and stored in plaintext (i.e. Password that is 123456789 might appear as 1469 in Klipper) unless I manually delete it. I tried to see if there was a way to disable Klipper history, but it does not seem so? 

Anyway, it was recommended to me that I make a feature request for an application blacklist for Klipper. For example, setting it to automatically ignore anything that has to do with Keepass 2. A blacklist feature would be really useful for individuals who have to run password managers, or individuals that would not want sensitive information in general to be stored in plaintext. 

Thanks for taking the time to read this, and thanks for making such a useful tool
