Paint,
I've gone ahead and whipped up a working code for Ursol's Vortex (works like all other targeting circle over mouseover spells), so if you wouldn't mind making this baseline, that'd be amazing. Saves me the trouble of having to re-apply it to your updates.
Additionally, placing this code just below PQI Config in the Rotation Editor allows it to work as a 1 Button Vortex + Solar Beam. Just make sure you map your Solar Beam to the exact same Keybind. Obviously you can change it to whatever keybind best suits you within the code itself. Enjoy!
if IsUsableSpell(102793)
and select(2,GetSpellCooldown(102793)) < 2
and IsRightControlKeyDown()
then
CastSpellByName(GetSpellInfo(102793))
if SpellIsTargeting() then CameraOrSelectOrMoveStart() CameraOrSelectOrMoveStop() end
return true
end
