I'd say that JAI isn't a 1 priority. More of a 2 like HN Tools. Extremely helpful when you need it but not critical.

I'd put the WME Chat Add-on to 1. It's the first thing I tell newbs to install.

I prefer WME Speeds over WME Color Speeds, but that's personal preference.

I find Open WME In GMM a useful script. Maybe 2 or 3. Probably not for the novice user.

I put JAI as a 1 due to it being important to build an understanding of the various forms of verbal instruction, and how the editor controls it. Level one editors can easily be interacting with sub-45-degree angles in residential Street areas. I'm surprised it's not built-in to WME yet

WME Chat as a 1 is strong point; modified accordingly.

I wasn't familiar with WME Speeds (so many SL plugins!). I added as an option.

I purposefully avoided Google crossover scripts such as ones that open the current view in GMM or Google Maps since they might encourage using unauthorized data sources.
