hi! i think there were some problems with using 'download' panel. have you tried using 'file' -> 'open' from the menu bar?
hm.. could i ask what os are you using? and if there are any errors in the console (view -> toggle developer tools)?
i would appreciate your help documenting the issue when you try it next time(◍•ᴗ•◍)
