Minor updates.

@ahuang11, does this existing FAQ answer address any of what you were proposing in Q: How can I access all the options that aren't exposed in HoloViews, but are available in the backend??

  from holoviews import Store
  Store.add_style_opts(Image, ['filternorm'], backend='matplotlib')

(Or should this bit be combined with yours?)

[ahuang11]

Ah, I wasn't aware of that, but that's pretty neat!

For the question Q: How can I access all the options that aren't exposed in HoloViews, but are available in the backend?, I used finalize_hooks / final_hooks in the answer because it can be applied to more cases. For instance one example from gitter:

"I need plain integer number on x/y axis labels rather than scientific notation. How can I format the axes ?"

def _add_int_axis(plot, element):
    p = plot.state
    axis = p.xaxis[0]
    axis.ticker = FixedTicker(ticks=list(range(0, 10)))

hv_obj.options(finalize_hooks=[_add_int_axis])

However, I believe your answer is more suited for the question, and maybe my answer of using finalize_hooks can be put somewhere else?

One suggestion for the copyable code:

import holoviews as hv
from holoviews import Store

hv.extension('matplotlib')
Store.add_style_opts(hv.Image, ['filternorm'], backend='matplotlib')

So it works without it complaining Image is not defined and KeyError: 'matplotlib'

Nevermind about below; can't have consecutive .. code:: python blocks.
Also, I noticed some of the code is not showing up in the preview, but I can't find what's different about this code block from other ones...

@ahuang11 , I think I addressed your suggestions; can you please see if that's now clearer?

[ahuang11]

I think missing **A:**

[jbednar]

Fixed, thanks!

[ahuang11]

Yes, it looks great! Thanks!

One additional suggestion I have; we probably should try our best to sort the FAQ by how frequent they're actually asked so that newer users don't have to read through the entire doc to find what they're looking for.

Right; the order is quite random right now. Ok, let's merge this one and then if you'd like to take a stab at identifying which are the most common questions and put those first, that can be a separate PR where it's just moving things around rather than adding new content.

Sounds good!
