People who ask to be able to run different developer tools at the same: are you able to give me concrete examples of what it is you're trying to do, and why you need to be able to run the tools at the same time? DM me or reply to this thread.

@Steve Goldberg Do you mean running the theme dev tools, extension and javascript local at the same time?

yeah; theme, extension and SCA source tools

what if an earlier setup exists where Extensions/workspace/Modules folder contains only Javascript and Suitescript files , but the template files are still being changed directly from Theme/…/Modules/….

Can you give an example?

Ex- earlier devs on project had Extended Order Confirmation Module. Later another dev came in and did the changes directly Theme template. 3rd dev needs to change just one thing the Theme/../ folder, and few stuff in Extension/…/Module folder

I need to customize the login page. need to add custom fields, need to re-order the existing fields in the theme and need to do additional validations. To do that I need to run theme developer tool and SCA source.

I need to add a data view to theme which will be the place holder for my extension. So I need to run Theme and Extension at the same time. Uploading theme and extension takes a long time. Example: I need to add a sibling div to Product.Sku and my extension will use that place holder to add the html template.
