ObjectDock 2 is still in beta. There is no manual or guide atm. If you had ObjectDock Plus version 1.9 all you need to do is copy the folder from any ObjectDock backgrounds you had installed and paste the folder in the ObjectDock 2 backgrounds folder.
ie: Tabbed in the Tabs folder and Tile in the Tiles folder.
I haven't found any need to adjust any config files to get them to work. Only need to restart ObjectDock 2 after pasting the new background folders.
Well..the problem is that the new version has lots of new settings and also uses different folder names (IE Zoomed instead of non-tabbed)
I didn't have 1.9 that long I only tried the trial and then immediately purchased 2.0 because I liked the program..my problem is I am having issues with commands..such as I can't find an option for the indicators anywhere like 1.9 had....also I don't know how to change certain things like the spacing between the seperators and things like that... 
Is there a document for 1.9? (Ill check your previous link)
Thanks
