Create Tray feature in HTML5's CANVAS for puzzle, Solve minor issues

I noticed some issues, 1. Some puzzle peices goes up and down if they are near to scroll space 2. Scroll is working on mouse scroll, not swipe. It should be swipe, or place a buttons [ at top to scroll up '/\' and at bottom to scroll down '\/'] if swipe is hard to implement 3. Some black-lines are visible when Ghost is Turned on. 4 and seemed to me like it was hanging [it may be issue with my pc being slow] 5. Puzzle Turn On/Off option is not working. I think you just need to use the flag, and put your new code in that "if" condition of the flag 6. and, when we move out the pieces and move in. there are many issues like overlapping and too much space in between... -----------older project, I want to add a Feature in my current CANVAS+IONIC/Angular App, 1) CANVAS (HTML5) changes CANVAS: Scroll bar for puzzle pieces, so user can easily slide the puzzle pieces and select the puzzle piece with ON-OFF button, best if puzzle pieces can be resized according to Jigsawbug game (feature with ON-OFF button in jigsawbug), JigSawBug, [login to view URL] Can check Image 1. It would be best if you have Scroll bar working example, or Try editing in the given JigSawBug source (Github code, [login to view URL]) first and then bid, if you could be make it work(scroll one puzzle piece) partially, then I would give first priority to that developer. My current status of application; [login to view URL] working fine, with Ghost On-OFF. And this is what I want... [login to view URL] Original Source code Demo of Puzzle game used in my application. [login to view URL] Github code [login to view URL] We have added Ghost feature later, so it's not in this. Payment will be done after completing. And source code must be given after payment. Thanks.
