Little Lock or little right click Menu for Lock and Unlock a Bitmap

[Subpath]

Whenever I need to lock or unlock a bitmap in VectorStyler,
I wonder what it would be like to have a small locking function
(padlock?) on the bitmap frame to lock or unlock a bitmap?

Or a small right-click menu just for that?

I find the menu option a bit impractical. I know you can create a
keyboard shortcut, but I'm a hopeless mouse-preferring user.

Here's a picture from CorelDraw. They're overdoing it with the number of locks;
one would be enough for me. But that's the direction I'm thinking.

Also, the term "Unlock all" even if I only want to unlock one bitmap
scares me always a bit. Wouldn't "unlock bitmap" be enough?

These are just my thoughts on this topic.. If anyone has better
ideas, I'm open to listening.

@Subpath In VS, the right click menu can also be customized.

I know I can customize the right-click menu, but my post was
about a standard solution, not a custom one.
