59:T467,

Primary purpose: provide an easy command to include in a macro to manually fix tainted raid frames. This works by having the addon click the checkbox for you twice at Interface>Raid Profiles>Keep Groups Together. Doing this refreshes the display of the raid frames.

Other options included: click the checkbox once (switches to other group display mode), force the checkbox to checked, and force the checkbox to unchecked.

Nothing to configure. Works entirely through slash command /ftrf or /FixTaintedRaidFrames as shown here (this is the in-game usage help):

FixTaintedRaidFrames usage

Include second argument "verbose" to get confirmation
