But is there a single example with DOpus integration that would e.g. set some of these column properties ScriptColumn [Directory Opus Manual] so that DOpus knows how to work with/style the custom values coming from that shell extension?
Like you have some old SDKs Plugins: Opus Plugin SDK updated and now available and there are a few examples of viewer/VFS ones, but there is nothing for columns?
Evaluator doesn't have access to item properties like is_symlink etc Item [Directory Opus Manual]?
Also, if I recall correctly, scripting columns have this multicol feature that allows to do some expensive calculations only once per multiple columns (you still couldn't avoid the per-item cost, but at least you could do whatever you needed only once).
Is this something that would be available for Evaluator (guess, not yet?) or Shell Extension columns (guess, not ever since they aren't part of DOpus?)
And then, let's say, if I wanted to get the file size data that DOpus has received from Everything, would that work with these Shell Extensions thingies or would this work have to be duplicated?
