I have been an active Freelancer on Elance for almost 8 years.
There is one feature in Elance which was very useful for Freelancers but is not available in UpWork.
It is the SEARCH by "Time Left" feature.
This feature lets the freelancers identify projects which are going to expire within the next 1 - 7 days, and accordingly plan when to apply to those projects. Attached is a SCREENSHOT from Elance.
As of now in Upwork, I have no way of knowing the TIME LEFT for APPLYING to a project.
At any given point of time there are hundreds / thousands of projects in a particular job category / sub-category and I do not know which ones to apply first, as I do not know the expiry date of the project.
I request the Product Management team to set up this feature as soon as possible.
That would be a great feature if jobs actually expired on Upwork, but as it is as long as the client logs in and looks at his list of applicants the job really never expires. There are several topics on jobs that are 2 - 3 years old on Upwork that still have not hired anyone and the job is still open.
