I am using Google Apps Script and was wondering if I could use any sort of editor outside of the one Google provides. (I purchased Sublime Text and would like to use that.)
The one Google provides is disgusting, with tiny text even though I have a giant screen and syntax colors that I find a bit difficult to distinguish on a white background with small text, and I don't have the beauties of Sublime like tons of custom keyboard shortcuts, all of my packages, etc.
Google has dropped support for Apps Script inside Eclipse but you can set up a local development environment inside VS Code using the Apps Script Starter kit and CLASP.
Here's a video tutorial to help you get started.
