Tooltip Icon mod:
Damn Tekkub
Flash alert for conflag warning would be part of Bigwigs. Navigate "Bigwigs > Extras > Flash'N'Shake"
Edit:
Never seen a dot timer that allows you to target a unit, especially not recast on the target. Your best bet would be to get a dot timer that clumps dots depending on which unit they are on and then recast yourself.
Basically I remember this:
You can't make mods that have clickable bars for all units nearby. A player has to be targetting them for this function. The way that Proximo circumvents this does not work with npcs.
