Original GitHub issue: https://github.com/open-webui/open-webui/issues/5486

Functions & Tools:

add on_valves_updated (like on pipelines, should be only a 2 lines patch)
let update Valves from inside the Function/Tool itself (that may be useful for plugins that wants to expose different user valves params based on global valves settings)
new icon management for Actions: as there is no way to embed an icon_url compatible with light & dark themes at the same time, please add icon_url_dark (any other alternatives that enable a way to have compatible colored icons on dark & light themes are also welcome)
implement decent logging for tools & functions

Valves:

add Comboboxes/Listview
add Textbox (multilines strings)
sliders for numeric values
Static text (single line like title, and another for multiline text for long descriptions)
allow user valves to be pinned, so each time we open user valves the same settings are displayed first

Additionaly: it would be nice if modifying the valves of a tool made it reload in a way that allows setting the tool description dynamically. My use case was that I'm creating a tool to add anki cards (=spaced repetition flashcard) and the llm needs to know the card text fields to specify when writing its tool call. I finally made it work using a @property setter that calls a function that updates the docstring which, rather confusingly, worked only when my placeholder was in the beginning of the docstring and not when it was in the :param line because of the way the docstring gets parsed. So if updating the param could be done too that would help, as that behavior seems undocumented.

This sounds like a useful feature! I'd be interested in contributing to this. Could you provide more details about the expected behavior and any specific requirements or constraints?
