Been looking at V4 and have to say it looks and feel fantastic.
Is it worth considering a toggle option to disable certain features. A novice/ Advance type thing. I can see a lot of people raising issues when files are missing, not understanding they have ticked them on the upload option.
On install the default is to EZG3 directory, how are you going to handle moving data directory to a EZG4 folder, another stack of support questions
If selecting upload to folder and leaving it blank - it allows this - the upload locks up with "unable to create directory" then"upload process cancelled - finishing action Please wait" only way out is to stop program, cancel does not work.
Alternating between folder or ftp also caused a loss of files being displayed, unable to repeat this one, rechecking.
