Select which assets to include and exclude in an export
Being able to choose which files to export and NOT export would be great. So that you can easily re-export all images of a UI without hand-picking every file you want to export. So a tag for include/exclude....(!) Should also work with groups so that groups of buttons and text can exclude the text in an export process.
Starting with XD 4.0 you can mark for export individual assets and export them in a format of your choice. Marking can be done using the layers panel. After marking, you can select the following menu sequence File →Export→Batch or shortcut Shift + Cmd/Ctrl + E.
Hope it helps.

So when I tried using this feature, I noticed in my icon export folder, I have a lot of duplicates of the same icon as it was used in several artboards, would be nice if using the name of the icon layer, Adobe XD won't duplicate the icons.
