Hi @Nithish-Sri-Ram this is a Native Kotlin ticket. Please align with @juliajulie95 first before continuing this ticket. Anyway opening a file picker everytime an image is saved is not the best for the user experience. I would suggest to add a section in the save image dialog for selecting a custom save path instead of the default.

@bakicelebi , I’ve implemented your suggestions and updated the functionality to allow users to save both images and projects to the specified path. @juliajulie95 , please review the changes and share your feedback.
