Granular placeholder settings for dynamic filtering

Description

The current Hide placeholders of blocked elements setting applies to all network requests. However, with a global block of 3rd-party iframe, I am finding it difficult to notice when the block is breaking a site as the space occupied by the iframe is hidden. I presume similar logic applies to 3rd-party script and image.

I would like to suggest more granularity in placeholder settings to show placeholders for certain class of filters while hiding the rest. Forgive me if this is not technically feasible or I am misunderstanding something.

Is that what you're suggesting ?

Kinda related, but not the same feature.
That issue is asking for more visible placeholders to help with identifying blocked features.

I am OK with the blank placeholders that currently exist, but I would like to show only some of them. Currently, if you set uBlock to show placeholders, you can see the missing iframes, but you will also see blocked image ads taking space too.

I was hoping that a more granular setting will allow the ads to be collapsed, while allowing the iframes to show a placeholder.

Where? There are no blank placeholders in uBlock Origin, that's why it was suggested to add them to uBO too, just like uMatrix has them. The ones you do see when you untick Hide placeholders of blocked elements is from browser, by activating that setting, uBO hides it from appearing.

Although, what you're suggesting can be done by differentiating ads and blocked iframes in two categories as blacklisted elements and blocked elements.

Blacklisted elements could be those which are blocked by a filter rule, if found, so in this case ads and trackers.

Blocked elements could be those which are blocked by Dynamic Filtering, so in this case iframes.

Blank as in just empty space that is not collapsed.
You can test in the link provided, disabling Hide Placeholders show more space.

Yes, I am content with the default placeholders. Perhaps I should have called them default or empty instead.

That was my thought as well. However, I left the implementation details vague in case further granularity would be desirable such as separate settings for images, scripts, and iframes.

I was unsure how useful that would be though, as I only block iframes.

A screenshot would expand on that better.

Would you like me to provide a picture?
It just be me toggling the Hide Placeholder setting though.

Or are you asking what @gwarser meant?

Duplicate of gorhill/uBlock#3619.

[Metaception]

Ohhhh, so uMatrix already has this so this shouldn't be too far-fetched.

From what I can tell settings.html needs a collapseBlacklisted setting and all the translations need a update. background.js needs collapseBlacklisted added too. These two seems straightforward.

But, it looks like uBlock just collapses any collapsible requests right now while uMatrix actually checks against the domains. This is beyond me rip.
