Nothing. We had to have someone train us on the thing if you can believe it's that unintuitive and it's still a complete mystery as to how one is supposed to accomplish the required tasks with it.
This is one of the worst designed time sheet systems I've ever seen. It feels like using an early 90's C-Panel with nonsensical icons and button combinations, an entire lack of helpful automation, and no consideration for how people would actually use the platform.
It is as ugly as an old version of excel to boot, but not nearly as useful. There's also little to no descriptions or help for users as they try to navigate the product, and doing so is best left up to divining the state of mind of the developer at the time he was pasting this pile of garbage together.
As an application developer being forced to use this product, I am now considering finding a new place to work simply because this product is so bad.
Find something more modern and go that direction. Don't let someone in your company pick this piece of junk for "business reasons".
Timesheet program for an agency. I have no idea what they were thinking or what god awful reason compelled them to choose this platform, but basically any real developer could do a better job over a weekend.
