A graphic Web-IDE plugin to use modules on your flash (using tve FlashString.js)

Thanks very much allObjects for trying, obviously I forgot to mention about the options, but you found it, yes you have to set a folder.
There is a bug that prevents the popup from opening when binary folder is empty, so put any file inside, until I fix it. The puzzle button is the one you want, the folder button is an old version that may not work.

Once you have the window from puzzle button to open, it will still say "no flashstring found", that mean you need to transfer to the board with the button top right from flash or module tab.
Here's a snapshot of the application newly installed:
