Been looking for a GTD app that fits like a favorite old pair of work boots, and just does what I need it to do without being fussy.

Big request, since I'm not only new to GTD, but also new to being organized. Not new to getting things done when they're repetitive or "known," but new to getting things done when I'm the one deciding what gets done, when, why, how, and for whom.

Things is simple enough to "get out of your way" and let you use minimal structure. But smart features let you get some things really right for yourself. For example, using tagging and then letting you filter by multiple-select tags and multi-level tags is simplicity made extensible.

I like it.
