If you want a verb:
Let's all jump on this latest change, document what bugs exist, and fix them.
- To start something early or ahead of others, in order to gain an advantage.
If we want to beat the competition, we should really jump on this project now.
If you want a noun:
Jump-something, e.g. jump list, jump issue, jump topic, jump task
You wouldn't be the first to use "jump" in a creative way. For example, Windows has a jump list, which it defines as:
A jump list is a system-provided menu that appears when the user right-clicks a program in the taskbar or on the Start menu.
This usage is not exactly the same as what you want -- it's things to jump to, whereas you want things to jump on. But you get to provide the context to your colleagues in your other communications.
Alternatively you could use your word, focus: focus list, focus item[s], etc., or the already established hot list, hot topics, etc.
hot: 6a: of intense and immediate interest
