My tech lead from two projects ago used post-its on a whiteboard, and one of the teams I work closely with still does. For search options, we used a 2D-grid, where the vertical axis was the component and the horizontal access was the state of done-ness (unassigned, being worked on, in code review, finished).
If you have a small, colocated team, this is basically ideal. There's low overhead, and the overhead consists of physically taking off a post-it and sticking it in the next column, which feels very satisfying. At a glance, you can see how done the project is - lots of post-its on the left means you have a while to go, lots of post-its on the right mean you're almost done. If you have components that need lots more attention, they'll show up as stragglers on the grid, and then you can either allocate more resources or cut the feature as appropriate. (In our project, that was usually self-allocation, because we didn't have particular engineers assigned to particular components, and each engineer was familiar with a few different components). If a lot of tasks get stuck in the code review stage, you know that it's time to lean on the code reviewers a bit.
