While discussing this issue napari/napari#8241 it was suggested that it would be useful to add a mapped slider so that we can have finer control of the attenutaiton parameter for amip. There are two modes. In log mode each decade gives the same space on the slider but it doesn't handle min=0. In power mode the min can be 0.

The original implementation was done by @TimMonko as part of a pull request for Napari.

AI Disclaimer: The code was largely generated by pointing Claude at Tim's prototype and requesting Claude clean it up, handle min=0 better, move it here, and make it consistent with the superqt style guide.

Hey @bnorthan.
Sorry for the delay, are you closing because you/napari/etc no longer want this feature?

[bnorthan]

We still want this feature. I'll probably re-open this in a few days. I closed it because we are still discussing our AI policy and how to open up pull requests to the sibling repos in the AI age.

It looks like you already have some Claude co-commits so I assume some level of agentic assistance is okay in superqt.

I rushed a bit opening this and we want to do due diligence making sure we give enough context and evidence of testing when opening AI assisted PRs.

Sibling repos... of napari?

I definitely don't mind AI driven PRs. They are actually more and more often equal or higher quality. For me, the onus is on the reviewer/merger, not the contributor. (And certainly, reviewers/repos are justified in having policies that they don't accept AI PRs, but I don't mind them if they are short)

So, feel free to just leave it open and I'll have a look soon. But if you'd prefer to tune it manually go for it :)
