Ahh! after alot of pushing and pulling from Git, I started working on my next feature. It is the way, you warn people, “Harry no more remains the same”. My feature tells you that the stuff in the cell has changed. And no it will warn you as soon as you do it in a particular session. So basically an expert typing hand finishes feeding data, finds out errors in the document and makes few changes, the corresponding cell data is coloured.
It is wonderful. The past data is saved and is compared with the newly entered one. If they are different, the new one is coloured. I find this feature so small, cute and interesting.
