There's 2 different programs called Amidock on the Amiga. I suspect this is where the confusion lays. The one that comes included with OS3.9 is soooo much better than the other one.
Confusion? I think not, Amidock from OS3.9 is an ugly piece of bloated crap.
ToolManager and Polynet are so much better and both provide a lot more options than Amidock. I have used both (Polynet and ToolManager) on Amiga OS3.x and MorphOS. For OS3,1 (what I use now) I prefer the older ToolManager (2.1b) but ToolManager 3.1 has a much nicer MUI prefs program.
