You can always put different tasks to different files (per project for example). There no need to hunt for todos; use `C-c \` (or `C-c /` for more options) to create a sparse tree. It supports the same queries as agenda tag searches. For example, `/!` to show all unfinished tasks, or `/TODO` for just the ones with TODO as the keyword. You can also use the timeline view with a prefix argument to see tasks in the current file (`C-u C-c a L`). Or you can restrict other agenda views to the current buffer (`C-c a < t` for a task list). Custom agenda commands can also specify their own set of agenda files (they can also be chosen by a function whenever the agenda view is created).
