I did a little bit of googling but still wonder if I missed something. Does Houdini not have a Node badge to show for example if a node has animated parameters, or parameter expressions? Because many times you need to animate many parameters on different nodes in a sop network for example. Coming back to the file later to hunt which nodes had animation can be painstaking and very inefficient. Likewise for parameter expressions. For now the only way I can help myself is manually color code nodes, which is easy to forget but is also not real solution. I know that nodes that have the time dependent badge in that little clock but it's not the same thing. since it just appears in all downstream nodes anyway
I just made a little mockup of what that may look like A for animation, E for expression...for example

might be useful, but the idea is to have a CONTROL node with all of the parameters you need or an OTL, that would solve your issue

That sounds completely unrelated

Being able to tell at glance if any node has keyframed animation or expressions would be useful regardless, similar to Nuke

Scene is rarely encapsulated as a single HDA

You may have several HDAs feeding into another etc.

Its always nice to see if any of them have keyframed animation or whether the time dependence is inherited from upstream or potentially introduced internally

I personally use certain color to mark my nodes with manual keyframes to at glance see them, a lot of them are already complex HDAs, so I fully see the OPs point

A lot of times you may end up digging through someone elses scene and you need to be able to do such detective work regardless

And you just came here to say "That sounds completely unrelated" without bringing any new info to the topic.

Sorry to not be clear
By unrelated I meant relating the need or no-need for visualization of a node having expression/keyframe driven parameters to any sort of HDA workflow or parameter organization

I think we all agree there are workarounds - typical Houdini style; albeit tedious ones; but also we should agree it will be an improvement and not an impediment to the software for something of the sort to be implemented. Houdini has this reputation of making easy things hard especially for newcomers to the software.
Creating an HDA you can, then soon enough you get to start doing UI/UX work when keys accumulate of all the parameters and you have to promote them; and things like these become overhead 9That you as animator don't need to bother with especially with tight deadlines)that would be solved by my suggestion. Case in point, when doing motion graphics with MOPS nodes, you get to key lots of stuff on many different nodes - falloffs, modifiers, etc. A quick indicator of where those keys are PLUS a little window to the side in the current context you are working in of a list pane that would collect all such parameters can be a huge time saver
