Name of the last screenshot appears by default while taking a new one

[deepindersinghbti]

Whenever I take a screenshot using CodeSnap and rename the file from "code" to something else and save it and then take another screenshot, the name of the last screenshot automatically appears in the file name box.

**Steps to reproduce: **

1. Take a screenshot and rename it from code to anything else, let us say "Screenshot 1".
2. Take another screenshot in the same/another file.

This time, the name "Screenshot 1" should automatically appear in the file name box, which I do not feel is convenient.
