make the line operations a top level menu. I use them so frequently and always have to locate it in the edit menu

You can make it less burdensome if you customize your editor right-click context menu to add only those Line Operations commands that you actually use.

Dear Notepad++ deveopers,

We are a Community of Notepad++ users, not the developers. This is not where feature requests are officially tracked; we have a FAQ that explains this.

Personally, as a user, I wouldn’t want any more top-level menus; there are already quite a few.

And even based on your definition of the edit menu being “sophisticated cut/copy/paste” (which I am not sure I agree with as the best definition of the edit menu – but I will accept it for the sake of this argument), I believe line operations (like remove blank lines, duplicate line, sort line) are at their core cut/copy/paste commands, in the same way that indenting, case conversion, comment/uncomment, eol conversion, and tab/space conversions – some (like the sort) are just more sophisticated than others (like delete blank lines).
