I work in a distributed office, and over the past few days I've been trying to find a "concept mapper", which helps us to make projects more concrete through flowcharts etc. The problem that I keep on facing is that the web apps which dominate the current market just don't cut my needs. They don't allow for proper exploration, and collaboration is a frustrating progress. We would gladly pay for a tool that doesn't ge…

#32I've looked a bit at what it uses: shapes drawn are vectors, the app uses Raphael (http://raphaeljs.com/) for drawing, and Pusher (http://pusher.com/) for whiteboard syncing.

#36I would definitely use it. Add a [T] icon for texts as writing with the mouse is meh!
Nice idea - great execution.

#37Here is my sketch: http://sketchub.com/view/d4b8fcb36fe4b078b100069bafebd352
I'm using a Thinkpad with Wacom enabled display and stylus. It 'should' say 'hello world' 3 times and have an underline after each one.
In the saved and view only link, it shows a 4th 'hello world' on the left and more slanted. It was erased before my real test.
It seems to miss certain strokes as you can tell by the sketch. Mainly straight lines. This might have been caught as trying to move the sketch area, but it did not move or register the line.
(As a control test to check display and stylus, I wrote the same text in OneNote and it was handled fine.)

#38The front ends seem to get desynchronised when two incompatible concurrent edits happen; this is a difficult issue to resolve, but one solution would be to change the data flow so local edits are drawn by the client on a transparent canvas, get sent to the server, and then get drawn on the underlying main canvas only when they are sent back from the server. The transparent canvas can be reset by the client at that po…
