Flow CSV Viewer and Editor 1.1.8 have been released. This is a maintenance release that fixes several minor problems that were found since the last release. In particular, the X axis variable is now saved between sessions. It's also now possible to split the main area to see two files beside each other. See the What's New section in the Help for details.
Microsoft Store users should normally receive updates automatically, but if not, open the Microsoft Store app and select Downloads and Updates in the menu to initialize the update. Users who bought Flow CSV Editor licenses directly from Waveworks will also receive the update automatically.
