[akshpatri]

Step 1: Clicked on Calendar on the top left
Step 2: I went through all the features, however, I could not find any problem in particular
Step 3: Visualization can be changed, in the button aspects, i.e, the button options that say 'today', 'print', 'search', 'add', etc. can be modified by choosing different color combinations.
