I’ve now implemented a new “subsort” filter that takes a subfilter and sorts the incoming titles by the result of running that filter on each one in turn:
https://github.com/Jermolene/TiddlyWiki5/commit/619c0752bd3c6e71d1fcdb74daa03cfe8257afe4 The OP should be achievable using a subfilter such as: [{!!value}divide{!!time}] With that filter in a variable called “cost” it could be used like this: [tag[tas]subsort:number<cost>] The new operator will be available on https://tiddlywiki.com/prelease <https://tiddlywiki.com/prelease> in a few minutes (you can check on build progress here: https://travis-ci.org/github/Jermolene/TiddlyWiki5/builds <https://travis-ci.org/github/Jermolene/TiddlyWiki5/builds>) Best wishes Jeremy > On 23 Apr 2020, at 16:46, si <[email protected]> wrote: > > > Thank you so much Eric you have saved me yet again!
