I miss 5 important tooltips

Dear developers,
just bought the game and would like to ask ‘for a little thomething’:
-I would very much appreciate if you would add a tooltip to each of the 5 sorting possibilities of the ‘round shapes’ in the main screen. In other words: In the upper menu you have ‘Icon Controls’. By clicking on it you get the 5 sorting possibilities. Please: either you describe in detail in the manual for what they are good for and / or add a tooltip.
I miss a detailed description and I think this is a rather important piece of the game concept.
Thank you very much and kind regards.

Thanks, ill make a note.
