The browser is a great for distribution (apps are just URLs) and security (web pages need to ask permission before accessing anything on your computer outside of their domain). More people should question the common belief that desktop OSes (without enforced app sandboxing) do a proper job at being a platform for utilities like OP's. When you download and run an .exe on a normal Windows pc, you're giving it read and write access to everything on your user account. It's bad that you're required to put so much trust in developers to run programs on typical desktop systems; this either ends up causing people to be extremely picky about what they run or to give out trust too freely and get bitten by malware often. Platforms like the browser which sandbox (web) apps and enforce a granular permission system are terrific.
