Yep, this is an obvious issue. I'm not a fan of using the gear in either case, actually - it is generally read as "settings" so doesn't mean a huge amount.

The best I can come up with is to use input-mouse-symbolic for devices and dialog-information-symbolic for details.

The mouse icon is potentially misleading, since devices includes both internal hardware as well as peripherals. However, nothing better occurs to me.

Simple patch to change the icons.

It's a shame that the mouse icon is now duplicated. Would a variation of "audio-card-symbolic" without the note be better/worse?

As for dialog-information, it would be nicer if it was copied in the icon theme so that this patch would reference "settings-details" or something like that, rather than reusing an icon that was present for another purpose.

> Subject: [PATCH] panel list: use appropriate icons for devices and details

"git log" on the file will show that the usual prefix for it is "panel-list: "

A little explanation in the commit message as to why each icon was chosen would also be helpful.

Here's an updated patch which uses the icons that have now been committed to adwaita-icon-theme. It hopefully has a better commit message.
