docs oddities

[CarloLucibello]

At the very top of this doc page https://fluxml.ai/FluxTraining.jl/dev/i/?id=documents%2Fdocs%2Fcallbacks%2Fusage.md

using FluxTraining
using FluxTraining: Callback, Read, Write, stateaccess
model, data, lossfn = nothing, (), nothing, nothing

Is that intended?

Also, if from that page I follow a couple of links and land to
https://fluxml.ai/FluxTraining.jl/dev/i/?id=documents%2FREADME.md&id=documents%2Fdocs%2Fcallbacks%2Fcustom.md&id=documents%2Fdocs%2Ftutorials%2Ftraining.md
but then i don't see any buttons for closing all those panes or for going back. Even the browser back button doesn't have any effect.

One last thing is that I don't see a link when visualizing the docstring of types/methods to jump to the source code.

Thanks for reporting! These are known issues in Pollen that I have yet to fix

• For the first code block (I assume this is from https://fluxml.ai/FluxTraining.jl/dev/i/?id=documents%2Fdocs%2Fcallbacks%2Fusage.md), this is supposed to be hidden.
• You can close panes by hovering over the tab list in the sidebar, but I plan to add a close button on each individual tab
• History is also only one-way right now, in that navigating by clicking updates the history and url, but not the other way around
• Links to source files are broken only on GitHub Actions where the packages aren't devved

I'll leave this open until I've fixed these things 👍
