Do not select outline when selecting objects inside outline.
Example: Create rectangle, select outline, outside, place two objects inside the rectangle, select the two objects using the mouse with left button/drag, the rectangle is selected also. I do this when I need to move the objects inside the rectangle or need to align them.
Provide a way to change the autosave feature. On a slow machine or slow internet connection, it disrupts dragging objects. I would prefer an autosave when I hit the carve button and/or at a certain interval.
Provide feedback (“Generating detail toolpath” with progress) during detail bit toolpath generation. If the carve is highly detailed, this step can take a while and nothing is displayed on screen - the window is only disabled. The first time this happened, I thought my computer had locked up.
