Copying a password or username or any other field is one of the most frequent actions, I am doing in enpass.

Currently: Right now you have to press this little icon on the right side of the field panel in order to copy or do a right click on it selecting copy or press the copy user/password shortcut with 3 keys.

Suggestion: It would be great to just left click on the whole field area to copy the information and also increase the size of the copy icon, if needed anymore anyway.

 

The show mode could be enhanced as well. Right now you have to click the small icon at the end. One problem is, that is is so small, another problem is, that I might want to show this information just for a blink second (e.g. for validation). 

Suggestion: Allow the secret information (all of it) to be shown, while holding a special key, when you are not in edit mode though. Other apps use the alt-key for this feature.

 

In KeePass you double-click the field (like username or password) to copy it to the clipboard.
And I agree that the copy icon should be increased.
