Optimizations and Fixes for long descriptions

Added:
- Show only names settings: in case of multi-line descriptions, only the first line is shown
- Shorten long descriptions: Removes all characters after x index, and add `[...]`
- Max length before truncation: x for Shorten long descriptions
Notes:
- If Max length == 0, then item names won't be displayed
