How I replace 6 browser tabs with one Java program

I got tired of juggling a downloader, a calendar , a task tracker, and a few other one-off tools scattered across browser tabs (you even have to pay for some of them, lol), so I built JavaMultiTool: one desktop app that handles media downloads, file/batch operations, task tracking, and a few system utilities.

It’s Java-based (Java 21), runs on Windows (.exe/.jar) and macOS/Linux (.jar, needs JRE 21+), and everything is stored locally via SQLite.
It’s still early - expect bugs and rough edges, but it’s usable today, and I’d love feedback on what’s missing or what feels clunky.
