A simple stylized sketching tool (replacing the current one) would be great. It works great for tablets and phones with drawing but for PC it is simply not functioning.
I believe this can be improved quite easily by adding some simple features like basic shapes, arrows.
Reason:
We try but cannot use Evernote for design documents. It would be great to showcase a development logic visually or a mockup for UI/UX departments or for creating flowcharts etc.
