Current way of creating and testing for example jscript buttons is painful: customize > edit button... type code then close editor window, then close customize window then test... repeat...
There should be a way to invoke direct button editing which allows to execute button's code by clicking on it while in edit mode and also have Script Output log opened automatically while in this script edit mode.
When can we expect better script editor? I think it is a necessity now that Opus has extended scripting support. Or perhaps there is already better way of which I am not aware?
