Highlight regular expression support

[DillonJ]

I've only recently come to appreciate the power of regular expressions in toolbox... particularly filtering the parameter value object_name_list column. It's very powerful. I wonder if it's well known and if it should be highlighted more in the UI that it's supported. At least a tool-tip perhaps... or instead of "search" you could have "search(regex supported)" or something ?

Indeed, we should advertise the feature more. For example, Exporter's Filter column uses a regular expression editor with a link to some documentation:

The placeholder text could also mention that a regular expression is accepted.

Ah yeah, that's exactly what I was thinking of - perhaps an idea is to do something similar in every search/filter field that supports regex.
