PTBatcherGUI: Buttons, Arrangement

I put this as a bug report, not a feature request, because I think the current layout is confusing:

What distinguishes the buttons on the right from those in the toolbar? Among both groups there are general commands (start, stop, ... /Remove
complete, Reset all) and commands that apply to a specific list item. I personally like toolbar buttons with icons better than those with text.
If there is a distinction to be made between different types I would do it as above: general/specific.
Could you imagine to use additional columns for the specific commands? Like e.g. in Thunderbird where you can do certain mark/unmark actions in
a list column. Of course not to replace the buttons, just additionally.
