Multicolumn List with Icons - Timing issues

[ssimop]

I understand that if the list is multi-column, then the comparison will be done with the string items of the first column, and then the row must be rebuilt with the cells of the row, possibly stored in several adjacent local str variables. It is implied that each of the columns of this grid have to be initially stored in arrays. Unless there is another simpler way to do it. Any advice is mostly welcome.
