This reminds of a situation I faced early in my career. We worked on a network alarm management tool, and some of us used to rewrite the tool or bulk of its features. To a point we finally arrived to invent our own tools to fill up the gaps in the feature set offered by the current tool.

It used to be one of the biggest reasons why we learned so many thing in comparison to the rest of the team(which was fairly big), to a point we could make a lot of very critical design decisions or write an application that could save hours of time for our users.

Its one of those axioms of software development I've learned, in order to do good work you have to do mountains worth of waste work.
