Lots of advancements in WSN's mapping functionality lately, as of 10.1.11 Beta 4. First, the issue of not having all possible pins on the category or search map at once is at last solved. By setting Admin -> Settings -> General -> Map Pins Loading Strategy to 'all', WSN will progressively load all applicable pins that are within the current viewport -- and when the viewport changes by drag/zoom, it loads anything needed for the new viewport. It's generally a quick process but there's a loading indicator bar to make it clear when it completes.
Adding a couple of new tweaks today: changeswitches and changesettings. These allow you to change the value of any switch or setting using your tweaks.php file, instead of using the admin panel. My personal use case is for my development site where I want to do my testing with reCAPTCHA and alertify turned off, but not actually configure the site that way because my release tools make the development copy's configuration be the default configuration.
As of WSN 10.1.7, reCAPTCHA will be enabled by default using shared keys with no domain restrictions. This will provide a better out of the box spam-prevention experience on new installations, avoiding the accessibility issues of WSN's internally-generated CAPTCHA. You may still wish to replace the shared keys with your own keys in order to have control over the challenge level (more human-friendly or more secure against machines).
Normally, WSN's CAPTCHA option is sufficient to stop spammers from submitting to your site. It can be a bit annoying to the submitter, though, and hard to read at times. It can also be defeated by the more advanced or specifically-targeted bots. Now you have another option: google's reCAPTCHA. reCAPTCHA has several advantages. First, it can be 'solved' with just a click in most cases thus saving the submitter time and effort.
It just got a lot easier to do a one state directory. By that I mean a directory where the category structure is all counties of a particular US state, or cities by county... not a directory of businesses in Yevgeny Zamyatin's dystopian One State. For a while, we've had options in the auto setup to choose a category structure of counties by state or cities by county by state. That works well for a national directory, but in many cases people just want a directory for a particular state.
