I'm working on this change, i'll update this ticket when ready.
Apologies for long wait.

The icons are now supported instead of labels.
If you have an active license, you can get copy by emailing me at [email protected]

Thanks

would also be interested in setting icons to text in row columns as Edit|Delete Save|Cancel.
How do i display/undisplay these icons and/or text in row columns?

You can enable / disable the row action icons, by setting it true or false. It is enabled by default in latest version.

$opt["actionicon"] = false;
…
$g->set_options($opt);
