BiotechABC - Practical tools for biotech & molecular biology

I built BiotechABC because I kept running into the same problem: small biotech tasks often mean jumping between different calculators, sequence tools and websites. So I started putting the most common ones in one place. The goal is simple: paste your sequence, run the analysis, get the result - without an account or sending routine sequence data to a server when it doesn't need to. We're starting with DNA/RNA, proteins, primers, PCR, FASTA and molecular biology tools. This is still early, so I'm especially interested in hearing from students, researchers and bioinformaticians: What tool or workflow should we build next?
