Generally I like and use the contextual buttons a lot.
But I have two problems with them showoing up on many (or all) input und textfields
For my personal use I could not get blacklisting to work, the contexual button always show up. I tried form id and texfield-id.
On our website, our users often edit their data. After login all users with kee see the contextual buttons in any input and textfield. I tested this also with a new keepass database with only one login.
Therfore I would highly appreciate a more sensitive / defensive approach, that would not need any interaction of the user.
