I would be fantastic to be able to define the annotations tools shown in the toolbar. Just like Okular does.

The idea is to customize the buttons shown in the annotation toolbar. Yo could define an "#0000ff 80% opacity underline" as your first tool, a "#ff0000 80% opacity underline" as your second tool, a "#ffff00 100% opacity highlight", etc.

As the number of buttons in screen is limited there must be a "More" or "Plus" button in order to show the rest of the tools and to access to the customization screen.

The benefits would be:

· Have a set of virtual tools like the one you use to have in the real world. Red pen, blue pen, yellow highligher, blue highlither.

· Being able to have several shotcuts to the same tool type (in my example the underliner tool) with different styles. Is a much faster way of changing between frecuently used styles of a tool.

· Being able to hide the tools you don't use. This you would access to using the "More"/"Plus" button.

Hi, now learning all about highlighting because just got a Samsung tab s 8.4 and I'm now reading a lot of pdfs for uni, have tried about 10 different apps for android and this is by far the best/quickest. I mark most text in one color, but often I want to chose a "headline" color, this requires two clicks, and then I have to change back when marking next part, so 4 clicks just to mark a specific word as extra important - what I would like is to be able to preset a specific color as a "headline colour" in settings, and then have that color as an option in the tiny menu that pops up, but it should just change the color for the selected highlight and not change setting so that the following highlight also is in the new color - to me at least this would save me a lot of time, one click instead of four, and I would be surprised if not other people too use highlighlighting with (at least) one colour that's extra important but not used as often. One option would be a more advanced solution with a customizable button where you could do what I suggest but also other things (that I haven't thought of yet). Cheers!

I do not know if it is possible thus if the Google Drive API provides functionality for it:

It would be nice to be able to work a Drive documents offline. I do not mean on "real" downloaded versions of these documents, but on versions similar to the "keep on device" functionality of Google's Drive app. Then if an internet connection is available again the annotated document is synces with Drive. This way it would be possible to work on PDFs from Google Drive on the road even if no mobile internet connection is available.

Maybe it is possible but I have not found this option.

I do not want to make a "real" download of a document, annotate on it and upload it back, since I use a folder structure in Drive that is simular to tagging. Thus I have a document at several locations and would have to upload it and set the location every time I worked on a document offline.

Thus the steps are:

1. Choose document that should be "kept on device".
2. Go on the road offline, annotate and have fun.
3. If an internet connection exists, sync changed back to Drive.
