I suggest you an option to not download all macro of demo, datasouces, images in local storage because i think this can slow the browser and it’s slow to delete all images from ui vision gui.
I think the download of demo macro must be optional, because can slow the performance of the browser (in demo macro there are a big amount of images).
I suggest you to add option to skip the download of all demo elements (macro, image, csv)
Do you want to download demo macros ? YES / NO
If I choice NO my browser will be more light and fast and NO demo macros will be saved in my local storage of browser.
