How do I change the legend position so it doesn't cover the plot label?

Before entertaining non-standard solutions to this problem such as building my own from scratch, is the a standard method for changing the position of the default legend generated along with a standard plot? I couldn't find anything about custom legend positions in the help sheets.

I can't help but wonder why this observed behaviour occurs by default? In what kind of plot would I prefer the plot labels to be obscured by the plot legend?

Can I open Maple 2025 files in Maple 2024? Further, what if the files don't use Maple 2025 features/packages? Does that change the outcome?

Does Maple 2025 have a dark theme or GUI color customization?

How to I generate and or export a plot without a white border or equivalently , just  the information inside the axes?

See example. Note that when I insert the content below, it fails to accurately copy the information( blue background). If you look at the attached maple file, it should be very clear what I'm after.

Can I define the creation and annihilation operator commutation relations with an explicit momentum dependence?

The goal is to implement an expression of a discrete scalar plane-wave solution to the Klein-Gordon equation that makes use of the creation and annihilation operators in the Physics package.

We don't bother solving the Klein-Gordon equation explicitly. Instead, we just take a solution from literature. This approach is sufficient to show the difficulty in defining the the creation and annihilation operators in this way.
