Feature Request: highlight processes by advanced filter

[timepp]

currently there are only predefined filters for highlights. It would be great if user can write simple condition expressions as filter criteria.
For example, one could write criteria like below and highlight it:

PrivateBytes > 1000000000 || WorkingSet > 1000000000

Supported operators could be: && || ! ( ) < <= > >= != ==
Supported properties could be anything available in column chooser.

There is one similar filter implementation I wrote for a log library, just for reference:
https://github.com/timepp/bdlog/blob/master/include/detail/logfilter.h
the above code accepts filter such as level > 3 && (tag = abc || tag = def)
