1) Drag and Drop feature
2) You select a folder containing all files. flinstaller and IL Download Manager automatically installs. (One Click Install)
3) Message: Have you done this download yet.
4) Message: You have already installed this Loop/Sampler/ plugin/program yet.
5) Message: All products purchased are already properly installed.
6) More files (.flinstaller) at one time. I need install one-by-one because the IL Crash with 3 or more files.
I hope this post help the developers.
Thanks a Lot.
