You can use SEDA, an open source application for processing FASTA files containing DNA and protein sequences. The Filtering operation (https://www.sing-group.org/seda/manual/operations.html#id5) allows you to filter sequences using different criteria, including sequence length.

" everytime a bioinformatician uses a GUI over a command line, God kills a kitten."

Not all users that need to deal with FASTA files can use the command line with confidence and efficiency enough to do their job.
