The current binning scheme results in the outermost bins having very few objects. This could be improved with bins defined by rank-order indices rather than array values.

Currently, there is a lot of functionality in `sim_manager` that is a pain to maintain. So in v0.7, some of this will be migrated to a separate "convenience package" that...

All current documentation of the bin-free CAM algorithm incorporated in #888 only covers zero-scatter CAM. I have no strong opinion on the optimal method, but I am unhappy with `noisy_percentile`...

The [delta_sigma](https://halotools.readthedocs.io/en/latest/api/halotools.mock_observables.delta_sigma.html) function raises an unexpected exception when run in parallel. Thanks to @SandyYuan for pointing this out. Until this is fixed, users encountering this problem can run delta_sigma on...

Thanks to @manodeep for pointing me to [this research note](https://arxiv.org/abs/1805.09550). Halotools is now in a feature-freeze for the soon-to-be-released v0.7, but this should be a relatively short-term priority since it's...

Implement a halo catalog that can be distributed across nodes of a large cluster using MPI

The feature being requested here is to be able to transfer the subhalo population from a high-resolution simulation into a larger-volume, lower-resolution simulation. There should be support for __masked__ selection...

The name change in #887 and #888 should be better explained so that users can understand the connection between the old and new algorithm. It may also be worth mentioning...

Current docs only list the default option for the `add_subgrid_noise` argument of `conditional_abunmatch` as "recommended" without evidence.

In the bin-free CAM implementation introduced in #888, the first and last `nwin` elements are treated using the naive pure python algorithm. For typical `nwin` values of a few hundred,...
