Fixed several glaring issues.
Name changed for clarity to adapt to the purpose of the tool. (Last time I promise)
And merged content will auto delete itself whether the user saves or closes the dialog as expected.
I just need to figure out how to prevent Krita from counting that as undo history.
And the other thing I really want to fix: raising the menu from the bottom to just below the other export options.
Try it out.
