Position of the button "Show HTML"

Is it possible to somehow move the "Show HTML" button towards the very left (or into the overflow dropdown menu "More")? Many thanks!

Often I continously click on "Archive", but for some/HTML mails the "Archive" Button jumps position when the "Show HTML" button appears. Especially in messages with attachments that take time to parse, the "Show HTML" button might only appear when the user already is about to click some other button in that area. (As there's the keyboard shortcut "a" for Archive, I actually don't really know why I also use the Archive button, though.)

Yes, the button in the message header area. Thanks for looking into it! Currently I see the following button order: Reply, Forward, Archive, Junk, Show HTML, Delete, More.

Perfect, buttons can be re-arranged (and also changed to display text and/or icon). Thanks a lot!
