Disabling icons altogether

Suite and Optimus Suite 5
#1

I can easily turn off icons for a tree, but not for a treegrid?

Am I missing someing, or is this a limitation?

I basically want to say NO ICONS except the plus / minus ones for the tree part?

I tried (a hack) by creating a blank icon (1 pixel by 1 pixel), but the treegrid still keeps indenting expanded lines as if there was a full size icon there!

You can’t fully remove the icons, but it possible to change their size or visibility through styling

.treegrid_cell img {
width:1px !important;
}

#3

This resizes BOTH the expand/+ and contract/- icons AND the folder icon!

I want to keep the +/- icons and just get rid of the folder / leaf icons?
