I found a post from more than a year ago asking about Macros, but of course the topic has been closed.
I’d love to see macros implemented on the MDI page as a set of buttons (maybe 6 or 10) that can be user assignable with G-Code.
The sort of thing I need to do is be able to remember/program several different start points.
I have a typical XYZ zero point at the front left, but have others I use regularly to machine off the front (end/side of pieces). I use MDI to get repeatable placements that than jogging and eyeballing it - I’m sure many others do the same.
Being able to send :
$H, followed by a G28 then set XY zero set XY to Zero
or
$H, set XYZ then G0 Xxxx Yxxx then set XY to zero again for multiple different points by clicking buttons would be really useful 
I do this in UGS on another (much smaller) CNC and it works well. Having this in CM would be awesome!
I don’t mind having to press multiple buttons if needed, but having to type out long strings in to a computer mounted at eye level and set back a couple of feet is less than ideal.
I’d also like to see a “home” button on the run page so that at the end of a Vectric job (which sends it back left) I can send it to the back right instead of having to do to Jog, then Rapid positions and then click the back right button.
