An Interface Fix
This is more of a fix than a suggestion. Whenever Split Shot gets activated on Medusa, an icon appears above where Mana Shield's icon currently is (bottom right picture). This icon serves no purpose other than to show the player that Split Shot is activated, but a better alternative is simply to remove the icon and replace the Split Shot icon with the engine BTNCancel.blp icon to show that Spilt Shot is activated.
The picture below summarises the suggestion:

The only way I could think of would be to replace it with an "invisible" icon, but you would still see it when holding your mouse over it (a tooltip without text).
Codability is not an issue; you can simply put the dummy ability in a spellbook and disable the spellbook. This causes the icon to not show.
For those who dislike the cancel icon, kirb has made another deactivation icon for Spilt Shot:
It would also be nice to replace Mana Shield's cancel icon with BTNCancel, since almost all spells in DotA have the standard cancel icon as a deactivation icon. This is, however, not part of this suggestion
, and I'll leave that to IceFrog and his team to decide whether or not this is best for the game.
