Gcode editor...tool change inst. Advance

Hi, I’m really new to gsender so far I do like it.
Here are a couple of thoughts, can we get a gcode editor. Even if it’s just a shortcut to note pad with a pop up that asks if you want to save the file if yes maybe have gsender reload the file??

On another note :
Tool change… It gives you 3 steps to go though for the change .
Instructions don’t advance, as you do the task you have to use the scroll bar to get to the next step. Otherwise not visible .At least that’s happening on my system
Thanks you
