@iZarrios Please make sure to check the filepanel and sidebar search functionality.

Make sure the searchbar width scales when terminal is resized and help menu scales.

Make sure to use fzf search

Make sure that when too many characters are entered in searchbar, it correctly warps.

Reach out to me here, or on discord for any help.

Hey, the PR is up now, I made sure to use fzf search, I am not sure with the current setup common.GenerateSearchBar() we have wrap? The default charLimit is set to 156. I made sure that the width scales when terminal is resized and also thats the help menu scales.
