Regarding 1, I will need more context to be able to answer your question. For 2, symmetries under index permutations are currently not supported. In general, it's quite hard to...

Yes I will need to change how I deal with this, I will try to fix this soon.

My apologies for apparently never responding to this. This is indeed nontrivial, I would have to learn about the internals of `BitArray` and even then it is not clear that...

I fully agree. However, I don't have the knowhow to do either of those at this point. Hopefully in the future.

Thanks for those. Should I keep this PR open while you continue reading and correcting? Note that the manual has become a bit outdated over the past year. I think...

Thanks; they all look great so I no need to cherrypick. The link to the confusing paragraph does not seem to work; could you just copy paste the confusing sentences?

I guess that could be done, but it's quite a bit harder than the other transformations that preserve stridedness. I guess it would require reimplenting quite a bit of the...

Almost all operations that you can do with `Tensor(Map)` objects, such as contractions and linear algebra factorizations, are currently only supported for `DenseMatrix`. Actually, in practice, typically only an implementation...

Not with the current functionality, `tsvd` is really supposed to be the counterpart to full `svd`, but with some more options, and an interface that I find better suited for...

In the public version, not yet. @maartenvd and others have been working on support for this (most of it is done) behind the scenes. Maybe you are interested to get...
