Hi there! This page used to contain a list of tasks that I was currently working on. Turns out, it takes a lot of effort to keep it updated, so I decided not to do that anymore.
However, you can find Thinktool's source code, as well as a history of all changes made, at c2d7fa/thinktool on GitHub.
You can also click on "Updates" inside Thinktool to see a list of recent changes.
