Hi there!
I'm a new user, and I have some basic questions about DataWarrior. Fist of all, I'd like to say that it is a fabulous software. However, one of the points that I just want to make sure is about the undo function (Crtl+Z). Does it exist? I have other few points that I would like to discuss in another moment.

Unfortunately, a general undo function would significantly increase the memory requirements and would mean a much higher development effort for many tasks. It also would come with a performance price. In the forseeable future an undo won't be available. Thus, before running one of the few tasks, which remove or change data (delete or merge columns, search & replace, etc), then a workaround would be to save the current state in a file. The majority of tasks should be less of a problem, because they can be reverted manually, because they only add columns, change filters or view settings, etc.

The chemical editor has an Undo, but admittedly, it is only one step. Multi-step undo would not be a big problem. The editor needs other improvements as well. Those will be done together, but this will be a matter of priorities...
