[DUPLICATE] Freeze Row Headings in Board view just like Column Headings

Hi,

For the same reason, row headings should be frozen too, when user scrolls horizontally past the current view port of browser window.

Thanks!

This is actually quite an essential feature. It gets pretty annoying not being able to see the row headers when scrolling past the current view port and difficult to move the cards between rows without knowing which row is which.
