I intended to delete an old workflow file in the workflow list. After right-clicking and selecting "Del," I found it wasn't deleted. I tried again, with the same result. Finally, I returned to the home page and went back to the workflow list, only to find that the old workflow and the workflow below it had been deleted simultaneously!
Even knowing about `script.robin`, I can't restore it. I can only rewrite the inexplicably deleted workflow.
This accident wasn't due to my improper operation; it's a bug in the workflow list causing deletions to display incorrectly. This is a serious problem!
I restarted my computer and then opened the PAD, but the problem persisted. Each time I deleted a process file and clicked "OK," the list didn't update; I had to exit the list page and return to update it. If someone didn't know about this bug, they might think they needed to click "Delete" again, which would be terrible!
This version also lacks import/export functionality, making it impossible for users to effectively back up process files/lists.
