VSys Anywhere tools are tools just like those in VSys One, except of course that they're used in VSys Anywhere!
Each tool has its own set of configurable settings, just like in VSys One, and these apply to one specific "instance" of the tool. For example you can have multiple "Person lookup (VSys Anywhere)" tools in a single tool profile, each with its own settings.
Some action links which show their data in a table using a datatable style allow you to override that datatable style. Doing so uses the Override datatable style or Override datatable style (mobile) instead of the default ones set for the site.
