i created this workspace because i like clean and simple layouts. i also like to have several custom subtool groups to keep things organised.
i use my dividers to customise the icons of the subtool groups.

tool overview:

the first two rows is where i keep majority of the default tools.
the second row are my custom tools that i use
the last row is where i keep gradients, shape tools, text tools etc.
subtool group example:
