Often when a collaboration on a project is over I wish to leave a shared folder AND keep a copy of the files for myself. On older Dropbox there was an option to do this via the desktop app, this option has now disappeared from the context menu. It is still possible to do this via the dropbox website. One must click an 'x' and remove oneself from a shared folder. Then one confirms this. After the confirmation a popup message comes up, where one must checkbox 'keep a copy of the files'.
The problem: I always found this so scary, because first I remove myself which suggests I'm going to lose the files and THEN only a popup comes saying - hey you can keep the files, a popup...
The solution: It would be more logical to have two options - "leave the shared folder and keep your files" and "leave the shared folder and delete the files" which one could select from and then confirm.
This option to keep the files is so hidden in the interface at the moment that even the chat support advised me to COPY a whole folder in order to keep it. That is obviously a nonsense for anyone who works with files that require correct paths to function.
