I finally published my chrome extension.
What it does:
Adds a button 'Notebook' next to 'Draw' button to open up notebook
You can store pieces of text (notes) in your notebook.
You can search your notebook for a particular note.
You can insert the note into the reply.
You can import and export your notebook, to back it up or share with others.
Where to get it:
https://chrome.google.com/webstore/detail/openstudynotebook/nmdboeolmlhaaepahmeklccofcbbmpdc
Filling up notebook:
Notebooks start out with only one benign note. You can import what I have in my notebook if you'd like:
```

```
Where are notes stored?
Notes are stored in a JSON array using localStorage.
If you delete your localStorage without backing up your notebook, then all the notes will be gone.
Firefox/Other Browsers:
I dunno if I'll make a version for other browsers, because I don't really use them. You're welcome to make look at my code and make your own version.
GitHub:
The code is open source, so you can look at it anytime you want.

Best ResponseYou've already chosen the best response.0It looks cool and promising. I am also trying to get rid of the longwinded coding required for latex display utilizing mathtype software. All equations may be exported or converted into MathML or varying Latex versions using the builtin translation of MathType. There will be no plugin requirement. However, this is only beneficial for those who have MathType software installed into their Mac or Windows.

Best ResponseYou've already chosen the best response.13What about the equation editor?

Best ResponseYou've already chosen the best response.0The editor is fine. I am looking for ways to be able to enter equations faster. it is a pain to use the equation editor and it doesn't allow a carriage return (new line). There are a lot of symbols missing also. Having to just click the quadratic formula instead of entering them character by character saves a lot of trouble

Best ResponseYou've already chosen the best response.13No, you have to back them up yourself.

Best ResponseYou've already chosen the best response.13Normally they're stored local storage. If that is wiped and you don't save them somewhere, then they're gone.

Best ResponseYou've already chosen the best response.0@Abhisar you just click "Note Library" and just copy the code and save it. In case it gets wiped you take what you had saved and click back on it and paste it there to get all of your notes again.
