- interrupting self casting is on my todo (i've written this in the revisions comment^^)
- Holy Light could be disabled by setting it to 0 (if this is what u want), else u can lower the default value (i think i did a very high value as default?!?)
- Multi-Tank Support should already be there, the tanks are stored in a list (updated with every pulse) and they are weighted higher than every other target (the only exception is if u set a focus in game to heal, than this focustarget is handled like a tank).
If this Multi-Tank support isn't working as intended atm, than i need a bit more infos bout your situation so that i can do some tweaks to the HealTargetSelection.
Atm there's only one thing possible u could try (but i think this does not fit your needs atm, cause i set this to a value which is much to high), you can set Priorize tanks (General Settings) to a value greater then 0.
This will Priorize Tanks over every other Player, so if your thank (and it does not matter if MT,OT or Focustank) has to be healed (HelathPercent <= IgnoreTargetsAbove -> means by default if a tank drops below 95 Healthpercent) needs heal your tank will be healed, and it does not matter if any other target needs more healing! (so be careful at this stage of development with using this setting)
This Priorize Settings will be tweaked in one of the next updates or gets a completely new meaning (something like "heal tank only" for some special fights)
I'm not sure bout this atm
