@peternlewis It'd be great to have built-in something like what the always great @DanThomas created:
a Prompt that asks before you import a Macro or an Action.
It'd be useful for new KM users as well, to know where do they want to place a Macro, or even more important, an Action downloaded from the forum.
Could ask to import the macro/action in a Disabled state.
OT: There are some great additions that should be shipped built-in, like a Progress Bar as well (also Dan provided an excellent macro ), or ship KM with more examples, like the Copy as Array, or how to Batch Rename files
