Some feedback and suggestions

[ffont]

I had the following compilation errors:

/Users/ffont/Developer/FreesoundUploader/FreesoundUploader/Source/FreesoundUpload.h:225:7: No viable conversion from 'const char [49]' to 'juce::URL'

/Users/ffont/Developer/FreesoundUploader/FreesoundUploader/Source/PluginEditor.h:571:7: No viable conversion from 'const char [43]' to 'juce::URL'

Fixed them by replacing URL url = "http://example.com"; by URL url = URL("http://example.com"); so URL constructor is used instead of converting from String. See JUCE URL class reference.

After the changes above I could compile the project. These are some comments.

• Had to disable VST2 target to compile.
• I can load plugin as standalone and I can log in to Freesound.
• Plugin (AU) fails validation in Logic Pro auvaltool so I could not use it in Logic Pro.
• Plugin loads in Bitwig Studio, I can log in to Freesound but I can't drop any audio (drop does not work).
• Using the standalone version, I tried to upload a sound and it failed, but no error message was shown. I was not able to do any successful upload.
• Would be nice to show uploading percentage.
• Make username visible when logged in. You could show the user avatar.
• Update color scheme to better match Freesound's design. Future Freesound design color scheme is similar to this: https://ffont.github.io/freesound-timeline/.
• I wanted to open a PR with the changes in code but I don't have permissions.
