Making Start Counting button more obvious

Before, Achieve Split count UI we have to take 2 Steps.

1. Click on the Side menu.

2. Find the start count button and click

Then we reached our goal.

But I have added a FAB icon on fragment Overview that help us to reach to split count in one Step

It improves UX of our User.

Thanks for the contribution, but I'm not quite sure if the FAB icon makes sense for a split count here
