Make system tray filter (icon auto-hide) open to the left?

I thought I'd revisit objectbar with the new version. I made a bar and it works, yay. However, I can't figure out how to make the system tray filter (auto-hide) open the hidden icons to the left instead of the right. What I mean is, right now, the bar grows to the right when I click the expand button. How do I make it expand to the left?

As for some piccadillos, I clicked the check to make the bar respond to the windows key but its not working. Actually, no hot key I set (and I tried like 10 different combos) brings the bar to the top. I think this option is broken. As an aside, there seems to be a bug with the bar autohide and object dock. If I use object dock to hide the taskbar then objectbar will only autohide to the top of my screen (opposite of where the hidden taskbar is). If I use objectbar to hide the taskbar it works but it messes up objectdock's drawer positioning. Lastly, when I check autohide, the bar does not automatically auto-hide form its last position. It will sometimes (happend 4 times in last 2 days) randomly move to various sides of my screen making it an interesting (though annoying) game of "find the bar" . If I check auto-hide and it stays in the right postion and I don't uncheck auto-hide, then it functions fine. Anyone else experiencing these? Thanks!
