SPICE edits and triggering sim

[psychogenic]

When editing the SPICE, changes are noticed by the system but it will only run the simulation once the textarea loses focus. It makes sense that we wouldn't attempt to run while edits are still being made, but it would be nice to have at least one of

• some indication that edits have been noted but are still pending (i.e. having a style for "dirty" textarea or something like that)
• some button like "run" (it wouldn't actually have to do anything as clicking would change focus); or
• some note about how to trigger a sim after edit (e.g. "press TAB" to run)

editing spice is advance mode and we might even remove it (though it's very useful for debugging). not expected to be used by majority of users.

also after editing spice the sim sliders don't work, and updating the drawing doesn't work. So it would have to be quite clever to allow those behaviours while still allowing spice edit

Yes. Might worth adding "(expert)" next to "Show SPICE" or "Edit SPICE" texts

definitely want the 'spice working' signal to show that things are being computed in the background
