Small update with great new feature:
Today I uploaded my latest build which contains a "Favourite-Browser".
This is to be used as little internal application which can store up to 1000 files in a desktop-style window.
You can simply add the actual DSK from JavaCPC's drive 0 or 1 to it, or also select a file from a filechooser.
You can also drag & drop 1 or more files together into the browser window.

The point is that you now don't need to search your most used media on your PC.
Each icon is stored in a config file and you quickly can open each file by double click on it.
On DSK files you can select the drive by right clicking on it and choose to load it to DF0 or DF1.
A few more screens:

Here you can add your files or cleanup the window by rightclick into empty area of the browser.

Typical right-click menu for a DSK file.
You can try the actual beta here:
