问题
Say, I want to develop an alternative spellcheck module to google docs. This means that I have to get corrections from my backend, and color the misspelled text's background, and do a small popup bubble when user hovers over it, where I'd display the correction. (please mind that spellcheck is not the actual goal of my project, but it does address my problems in a more simplified way)
What are my options? Any ideas how to do this?
Few possible solutions I came up with:
Chrome extension vs Apps script
Chrome extension
- pros: user has to grant permissions once, can freely traverse and append anything to dom via content script
- cons: is a "hacky" way, if google changes classnames or js source, it would stop working, and also, reverse engineering google docs's editor engine is impossible
Apps script
- pros: supported by google: if it works, I dont need to be afraid of docs updates
- cons: it seems to me that I can't just fiddle with the dom (because of Caja compiler), has very limited support (if any) for custom highlighting or hover functionality.
As I see it, neither of these are perfect solutions for this project. What do you think? Any suggestions are very welcomed.

I know this is an old question, but I have recently gotten into the same problem, and believe I have a solution. So for future Googler's I will post my answer here.
My solution was to create a Chrome Extension and understand how the Google Docs DOM's are structures to interact with it.
You can find my code to work with the Google Doc DOM's here

In Apps Script you can't "fiddle" with the DOM and you won't be able to implement hover functionality. Also, a lame Highlighting would involve changing the current document itself (which would go to revision history, undo queue, etc)
Therefore, your only altertive is the Chrome Extension. But I agree with you on the cons. It is a super hard task that could break at any minute without notice.
