I submit that the current Opus taskbar icon should be changed (out of the box, as it were - and not just post-hoc, via a procedure that does, thankfully exist, and which is described here).
For, at present, the Opus taskbar icon looks like . . well, like nothing with which I am familiar (and even on a big screen. If we enlarge the icon, thusly,
then, well, it still resembles very little. A sweet or a peanut with a plaster on it? Pacman with a cufflink?
What ? Sorry, I don't understand this part.
We do have these beautiful icons thanks to @pro.

@pro includes full instructions on how to use them as taskbar icons.
I don't use them as taskbar icons though.
I made a Dopus .dis icon file out of them and use them as a Menu Icon for Foldercontent buttons.
But that's just me. The icons are worth something and their value exceeds my current use of them.
I kindly disagree.
You tell me what the Adobe icon in your screenshot represents and I'll tell you what ours represents 
Hmm.
Perhaps the best type of icon is one that clearly stands for something.
Perhaps the next best is - as with the Adobe icon - something that, though not exactly pellucid, does not make the mind struggle to parse it.
But, hold on: perhaps the only reason that the Adobe squiggle does not boggle is . . familiarity.
Yet, even if that (viz., 3) is so, Opus could still aspire to have the best type of icon. Within the image that I submitted, the Sublime Icon, I think, falls within that class.
@David: you and I refer to one and the same way of changing Opus's taskbar icon.
That's ok. A product logo is not a pictogram.
It does 
but you'll have to answer Jon's question if you want the answer (or search the forum as it has already been stated).
After a few weeks (and now years) of using Opus, the familiarity with this icon is definitely acquired.
Which will go against the familiarity you just mentioned. You want something different, which is fine, make it and use the process provided to change it
Hello!
Jon asked what the Adobe icon represents. Answer: it represents the Adobe reader program, though it - the icon - does not resemble that anything in the look of that program. So, the Adobe icon is not the best type of icon. I do not think that I claimed that it was - see the point that I numbered 2.
On the impossibility of an icon being both new and familiar: oops; good point. I suppose I'll have to give myself a year or so to get used to the 'biscuit' icon (as one might call it). Or else change that icon, which is what I am doing at present. (I have the icon set to the Windows Explorer icon. That Explorer icon does look a bit like a paper file.)
We aren't changing our icon and decades of branding just because you don't like it.
You seem OK with Adobe's icons, and Chrome's and all the other ones that are abstract shapes and squiggles because you're used to them. You'll get used to the Opus icon as well.
