Ability to control file size on export without plugins

Problem
As a designer exporting assets for web development it’s frustrating having to either export with no control over the file size and reduce later in photoshop, or pay for an image compressing plugin that is helpful, but exports as zip files so the file management gets messy quick.

Solution
Have more expansive export settings e.g. slider for image quality and file size calculated in real time with slider - similar to photoshop.

Might just be me but I sorely need this functionality, especially during the rapid part of a project which is the design to developer hand over. Does anyone else have this problem? 🙂
