@bpostlethwaite this resolves two feature requests of yours from last December. |

nice! Will be interesting to integrate this back into Workspace |

hmm, nonblocking as this isn't new, but seems funny to categorize '=' in INEQUALITY_OPS. How about COMPARISON_OPS?

wait, do you mean with connectgaps set to false? connectgaps: true would run connect right over the gaps you just preserved...

Oh right. Good eye. Thanks!

Are there any interesting cases to test with two filters applied in sequence having different preservegaps values?

Not yet. I'll add one in a future commit 🚀
- add COMPARISON_OPS list - fixup `preservegaps` description - add `preservegaps` commute tests
