I haven't used Opus for the last few days (or weeks maybe), and after updating today I noticed I couldn't open archives with a double middle-click (using Go NEWTAB=tofront,findexisting), like I used to since Opus 12, if I remember correctly.
I spent about 15 minutes looking into why and found that the culprit seems to be the findexisting part. It looks like there have been some changes to Go in the recent releases (including betas) that might be related to this.
Is this a bug, or is this now how the Go command is supposed to work with archives? If so, what's the new equivalent? I just want to open the archive as a folder, and if it's already open, bring that tab to the front.
