Custom Menu & Notepad please

Hello,
how about the possibility to create a custom menu in GUI?
Maybe as a drop-down at the top navigation bar (header > navbar) next to the Terminal button.
For example»


Also a way to save notes would be nice.
If I use the file_editor module and edit the URL for e.g.:
index.php?module=file_editor&file=/root/notes.txt
this would do …, but I don't want to edit the URL everytime.

So therefore a custom menu or maybe a module/button just for notes.
Thanks!
