For example I have a couple WordPress installations (that serve specific functions) on the same database. During installation I can select a custom table prefix for all the tables that installation creates in the database. All addons I install also automatically get that prefix. That way there are no conflicts.
Does XF have such an option? I didn't see it during installation. I notice that all the XF tables start with xf_, but what's to keep an addon from using something different. Can I force all tables related to a specific XF installation and whatever addons to start with "foo_xf_" or whatever?
