Is it best to keep tool suites like this all in the same repo, or should I move each tool to a separate repo? I tend to prefer the latter, but I'll go with consensus.

@gregvonkuster I'm not sure what you mean with repo. But a classical suite are many tools that are in one folder, share one-or-many macro files and are demultiplexed into many TS repos.

Ok, thanks, I'll keep it this way. I'll add the fixes for the 2 additional tools - should have done that in the initial commit. ;)
