"Budget" and "budget left" should relate to money not time
Until I tried using the "budget" and "budget left" fields I had no idea they related to time. The word budget is rarely used in the context of time and almost always in the context of money.
As there are other fields relating to money under this tab it makes it even more confusing and strange to use "budget" in relation to time, not money.
Better would be for these existing fields to be labeled "time allotted" and "time left" (or similar).
A "budget" field should relate to the money allocated for the task and "budget left" should be for the budget money, minus hourly fee times hours worked so that we can know when we are approaching the amount of money budgeted for the task.
I believe it is far more useful to know when the budgeted money is running out than time allotted.
Perhaps better yet is to have all of these fields represented - time allocated, time remaining, budget allocated, and budget remaining. But at least, the word budget should be used in its usual context and meaning - money.
