Hi, gang. :-) I took last two days as holidays, to let the pressure out a bit, and used them to have mere fun with a few things, among which, Org Grep.
The tool used to have one main output, with Emacs commands to transform that output "one-way" into two other formats. I shuffled the code and added more, so it can switch freely between those three formats, now called "views". Buttons on the title line ease that switching. 1. The [browse] view is read-only, with a few extra Emacs commands. 2. The [edit] view is full-Org editable, and uses transient checklists. 3. The [tree] view regroups grep hits by directory, hierarchically. Org Grep yields [browse] view initially. When there are many hits, one can switch to the [tree] view and go pruning, using C-x C-c C-w, say, retaining only what is most promising. Then switch back to either [browse] or [edit] on the reduced set of hits. Convenient for me! :-) François P.S. For the curious, it's still https://github.com/pinard/org-grep .
