ObjectDock Plus is great, but missing the following important UI features in the tabbed dock:
1. Mouse over activation, should bring up the tab which you hovered over
(so that only one click is needed to activate an application, a delay maybe needed if dock isn't visible)
2. Placement of 'Dock Entries' should have other options, apart from align left
(you want to be able to place icons which you use most often near where the tab is)
also, not so important - but the normal dock, it should be possible to use hotspot activation when autohide is used - as if the dock width changes (ie. when using system tray/running tasks)- it's impossible to know where to throw your mouse.
Apart from that, great app!
