Is this "Blocks" How-to still good with the shift in adding everything as Packages?
Suggestion: Since I clicked the Ask Question button from the How-To page, maybe if it auto included that How-To title into the subject line. I posted this then viewed and saw no one else would know what I was talking about.
Yeah, it is. if you're developing a site for someone else, building a regular block that you just stick in the blocks/ directory and install is much easier than making some custom package. Same with themes. You only need to go the package route when you wish to bundle up multiple items and distribute them in such a way that they can all be installed together (and downloaded from our marketplace.)
