I need a wizard to optimize this interface to make scrolling of the tables faster: [url removed, login to view] You can make new lines by selecting a row in one table and then the other. Try making hundreds of such lines and you will see the performance problems caused by the lines when you scroll either of the tables. The purpose of this project is to make scrolling of either table perfectly smooth. You can achieve this by starting drawing the lines after the scrolling has stopped, and not all the time while scrolling is on-going.
I am only willing to pay 50$ maximum for this project. You must be able to make a pull request with your changes on [url removed, login to view] in order to complete this project. If you do not know how to do this, then please investigate this before looking into the project.
