That’s a great idea – whether it’s a tooltip or resizable. Unfortunately, we fellow Notepad++ users in the Community don’t get to make decisions about such things. I suggest following our Feature Request FAQ to make the feature request in a place where the developer will see it and could make a decision about it. (As the FAQ says, make sure you search the existing issues – both still-open and already-closed – to make sure no one else has requested that – and upvote it if it already exists)
