What's Exployer mode.. Sounds cool! 
Hehe, i've been staring at that for i don't know how long and only just realized.
My Opus says "Explorer" so I suspect the typo is from you renaming the tab at some point (unless you're using a translation of Opus that looks like English for every other word).
Really?
Ok thanks Leo, looks like i'm the one who can't spell.
I didn't know i could change/edit these, and i don't know how to even after i just searched. Also no translation, plus my Opus config is virtually default besides entering "customize" mode to add some buttons.
Very strange, it's been a long time since i touched any settings in Opus.
That's cool than, "Exployer" is fine i don't use that one. 
Right click on the tabs and select rename.
That "Misc Transfer" style tab right next to the one in question isn't part of the default config. Maybe you've been editing the style tabs in your sleep?

I'm going to assume your being serious here, and say now that's crazy!
If i hover over that "Misc Transfer" tab the tooltip says "Single Display, Viewer Pane" so i sure have done a lot of typing in my sleep.. I've never used that mode in my life and i only ever use one view.. ever 
Thanks Steve, i've never seen "that" menu before either. You know, it's really tempting to leave it named "Exployer" as an eternal reminder of my stupidity/strangeness however thanks... Renamed. 
Do you have a cat? They're always up to mischief when your back is turned.
If it wasn't the cat, perhaps you imported someone else config files ? Either that or you need to increase the medication.
