Since PB2017R2 until PB2025 BETA, the Add to source control dialog includes all files located under the Workspace/Solution's Directory.
But afterward, only PB objects can be manipulated through the GIT related menu options directly from the PB IDE.
It would be great if we can manipulate directly from the IDE files like .INI, .JSON, .XML, Images and subfolder contents that can need to be version controlled and deployed with the final executable. 
Implementing this will enhance greatly the overall productivity of PowerBuilder developers.
