Also, scaling tools to more than one user is incredibly hard. Software development is still custom / art. This tool works because it is suited to OPs workflow and his "way of thinking". In order to make it work for others, it needs lots of improvement and generalization, which is incredibly hard. Some people may even hate it, because they have their own best way to do things.
Devs should stop being delusional about their self-importance in these things. There are 100 other factors going on in an org and your one little tool ain't gonna make a penny difference in the profitability or productivity of the company (unless you have data to prove it, including impact on profitability)
