I like that it's easy, fast loading system with minimal distractions or interruptions from other windows while uploading your new pictures! It would be great if there were more options available (besides just upload).
The only thing we don't really use is "share", but sometimes this option comes in handy when needed without opening Facebook/Twitter etc.. If you're looking into photo editing software then go ahead-it works well as far image selection goes anyways because of its simple interface compared too others out here who seem complicated at first glance haha :P But seriously though - they do an excellent job overall so no complaints about anything specific aside form what was mentioned above ;-) We've been using Filmpixel daily since June 2014; our clients love how quicky everything loads up once uploaded via FTP access through Filezilla client!! That makes things easier than doing all by hand manually every single day!!
