thanks for your kind words. I am glad you like AmiKit!
Sure you can change the position of AmiStart taskbar! Click&hold right-mouse button over "AmiKit X" button, select "Taskbar Settings" > "Miscellaneous" and change "Taskbar alignment" according to your preferences.
For more details check AmiStart's HTML documentation in AmiKit:Utilities/EXPANSION/AmiStart/Documentation/ folder. Click&hold right-mouse button over "index.htm" file there and select Open in IBrowse, for instance.
Btw. I strongly recommend to backup AmiKit:Utilities/EXPANSION/AmiStart/sm.prefs file first! Such experiments with AmiStart config might go wrong easily, especially if auto-save option is enabled
