Whenever I use the web-client I get so annoyed at the constant re-drawing and re-organization of the screen.
I go to drop box, and select "All files".
I get a list of files, I would typically click on the folder or file I want
However in the background it's still loading items that will "Re-size" the screen, causing the list to re-draw and almost every time result in the wrong folder or file being selected as its location on the screen moves between you clicking and it accepting the click.
You have to always pause while the screen re-draws and re-sizes two to three times before being able to start any activity.
Using webclient to access a file takes 5x longer than needed while waiting for each screen to fully load and re-draw, even though the actual file/folder list appeared quickly.
