Hi,   Is it possible to create invisible UniFileUploadButton? What I want is just an overlay above any component that if you drop file there it just uploads. Now there is TUniFileButtonUpload where if you disable button look it is still dotted lines around him. Also I would like to be able to disable click on it. Would I be able to click whatever is under him if you disable click?   Maybe you can make any component event that acts as a drag&Drop for files...
