Glad to hear you are up and running again.
A suggestion…
Jumpstart the refreshing of your memory. Watch some of the tutorial videos.
I find reviewing instructional videos at 2x playing speed to be less frustrating… with Closed Captioning enabled and translated to my native language. (For example, @PLegoux has a few YouTube videos where he discusses Gramps with users … but they are all in French and I only speak english. So I enable YouTube’s auto-generated captions… which are also in French and I read French very poorly. So I use their auto-translate captioning option.
(Fair warning: the Auto-translate is confused by “umm” speaking hesitations… aka filler words. And filler words are common in any demo video where a narrated task can be more quickly “said” than “done”. So French “ahh/uh/umm” {“euh/hien”} are inserted as best-contextual-guess words in English. I wasted a lot of time looking for the Umm French feature. It seemed like it was used extensively on almost every advanced technique!)
