Working on a brief that is due tomorrow. Time is of the essence. I changed the names of many files & folders containing court forms. Very tedious but had to be done. When I finished & now ready to work on those forms: THEY'RE ALL GONE! What? 1000s of court forms--simply disappeared. I finally stumbled online & figured out that, according to Dropbox, I deleted those folders & files. No way could I have accidently deleted so many files & folders! So, instead of working on my brief that is due tomorrow, I then had to figure out how to restore 1000s of files to my computer--still not sure I did it right--the interface was not overly user friendly--& wasted too many precious hours in the process--including writing this message. Just now, I finally got back to real work--I renamed a folder & AGAIN, it disappeared!! WTF? I do NOT want any fancy new features; I don't have time to figure out what local, online or smart sync means nor do I care. I just want everything to work like it always did. I cannot be wasting time being hijacked by features I didn't ask for nor do I want. I don't want a new learning curve. Don't ruin a good thing. The simplicity & reliability of Dropbox were its best features. Add all the new features you want but give us the option about whether or not we want those new features. I feel like the victim of a bait & switch.
