spreadsheet: improve usability when dealing with multiblock datasets
Open can.ex2, show in Spreadsheet view. The view is showing two blocks: "Unnamed block ID: 1" and "Unnamed block ID: 2". As you are scrolling down, it's not very obvious which block you are looking at.
One way to improve this is add a separator row which shows the block name. As one scrolls, this row should anchor itself to the top, and hence never scroll out. Thus, making it easier to know which block's data is being shown.
