It will be easy to test blue sky scenarios if users able to modify values of local variables while debugging a process.
Variables can be modified while debugging from the Local panel as of 2019.10.1, from the release notes:
The Locals panel now shows the values for arguments, the properties of the current and previously executed activity all in a cleaner design. The values of variables and arguments can be modified from this panel when debugging is paused. Right-click a variable or argument in the Locals panel and add it to the Watch panel to continuously monitor its value throughout the debugging process.
This is awesome. We have 2019.4.4 in my shop, will try in my machine. Thanks.
