Tab Mix Plus

I'm referring to this,

http://tmp.garyr.net/help/#Events_-_New_Tabs

I have the following 3 options ticked,

Open other tabs next to current one
Only if related to current tab
Change opening order

The tooltip on "Change opening order" mentions in brackets "since it was last selected." It causes this behaviour,

[a][4][5][6][1][2][3][b][c]
Assuming that 4, 5, 6 is opened from tab "a" after tab "a" is last selected.

Is it possible to add an option without "since it was last selected? I would like new tabs spawned always to the most right, irregardless whether it was last selected or not, so it would be like this,

[a][1][2][3][4][5][6][b][c]
Again, assuming tab 4, 5, 6 was opened after tab "a" was last selected.

I'm using Firefox 13.0.1, with TMP 0.4.0.3pre.120518a installed

Lastly, I would like to say keep up the good work, I started using Firefox when it was called Firebird, with Tab Browser Extensions that slowed everything down, then made the switch to Tab Mix, then the original Tab Mix Lite (that went bust) than TMP (fast, quick, and loads of features), and it's always the one extension I regularly check for updates.

i'm not sure that this feature is needed by others

Fair enough, but what is the reasoning behind "since last selected"?

It would be simpler without it.

-EDIT- On second thought, this is how Firefox behaves by default, if anything I should bug the Firefox team about this.
