KimimaruNext up is linking with macros! Internally, what this does is simply put all the macro inputs into a grouping. As a small optimization, macros with a single instruction (standalone or linked OR a grouping itself), are not put into a grouping to speed up the processing done by the input handler.
Finally, a long-awaited feature players on #type2play have been asking for, which wasn't possible until now: permanent holds! Using the prefix modifier ^ it'll never let go of the input unless explicitly told to. This is useful in games like #supermariobros or #banjokazooie where you hold down a button to move faster. Players would get around this by holding the button for a very long time (~2 minutes), but with this it'll no longer be required!
