With strict Mouse-only usage, the ability to customize the Columns is located at the uppermost part of the context menu, hence faster access and more convenient. While the Tag Panel counterpart is located opposite at the very bottom.
As seen in the two sample pics, if there are numerous context menu entries already, then the Customize and even the Load/Save Customization context menu entries are too far below requiring a very long time to scroll down and left-mouse button hold-click.
I'm hoping for a change of the context menu location, especially since the Columns counterpart in fact exist at the uppermost part, hence it's apparently possible to be placed like the same? Thanks in advance.
I think one area where the route via File → Options comes short is when loading and saving configurations (it's possible, but also includes more distance covered with the mouse).
I've moved the configuration options to the top of Tag-Panel context menu with Mp3tag v3.28c.
Thanks @Wakaku for this brilliant idea and a big thanks to @Florian for making this improvement by putting Customize... at the beginning of the list, it's GREAT
