fix: trimmed long file names for better UX (#760)

Fixes #755 

### Notes for Reviewers
- The max length of the title is set to be `16`
- If the length of the title is <16 it returns the original one.
- Or else the title will be the first 8 characters (start) and last 8
characters (end)
- The truncated file name will look like `start...end`
