Following @rauchy’s PR to indicate unsaved changes when parameter settings are edited, I’d like to discuss the issue and offer some approaches.
Currently, there’s no indication at all that user should save query upon changing parameter settings. Low hanging fruit is to implement the current asterisk indication.
But since there isn’t a clear correlation between parameter editing and query save button, this indication might go unnoticed.
Change Save button color (yellowish?)
Show explicit text “unsaved changes”
Auto save, with discard button.
