There are quite a few users out there who use a lot of custom code within their Webflow sites and if Webflow implemented Emmet or an equivalent option would make writing code in the editors a lot faster. In VS Code, CodePen and other apps for example we have the ability to use shorthand entries to help auto-complete lines of code to make writing it much faster. API's for this are already available, it would just be nice for Webflow to offer it.

An example for those not so familiar with it.

Writing just link then hitting "tab" would generate:
<link rel="stylesheet" href="">

Once generated, the cursor is in between the href quote marks ready for you to add the url. You can see how much faster this is.

Along with this, it would be great if Webflow's designer could execute Javascript. This way we wouldn't have to publish every time to check our work.
