Ah, well that's much nicer ^_^.

Yeah, after I wrote the email I realised that all 'copy' does is stick a
file: URI in the clipboard slection, and cut just does the same thing,
except unlink the file on a successful 'paste' elsewhere. But yeah,
I'll just do as you say and copy ThunarClipboardManager. No need to

Yeah, after all that talk about the DBUS service, I totally forgot ^_^.

Yeah, I know. I probably won't use them myself (I've gotten pretty used
to no taskbar with the CDEish icons, personally), but I thought it would
be fun to implement.

Understood. I thought about the non-UTF-8 issue after I noticed that
point in the API docs, but I forgot to go and fix what I'd already done.
Patch looks fine; I'll apply it when I'm a little more awake and can
actually read ^_^.

Yeah, that was just not so bright. Don't knock your documentation - I
found using thunar-vfs to be *incredibly* easy due in part to the API
docs. Though it seems that all the stuff in thunar-vfs.h (aside from
_init() and _shutdown()) aren't documented for some reason. That
confused me for quite a while when I couldn't figure out how to do
something as simple as read all the files in a directory.

It's close enough ^_^. Thanks for taking the time to go over it and
fixing my mistakes.

Yup, that was the plan. I sat there with Thunar open, and stared at the
menu and the rename/delete dialogs for a while ^_~.

Cool idea. Maybe post-4.4 though ^_^.
> BTW: Do you plan to make the icon size an option?
I hadn't originally, but I really think it needs it. An 8x6 grid on
1024x768 (damn laptop) probably isn't enough for someone who heavily
uses their desktop for storage. I'm probably being a bit over-generous
with spacing and padding, too. Anyway, shouldn't be too hard to make it
If I don't get to your patch in a couple days, feel free to bug me.
I'll be back from France on Sunday night, but then I'm leaving for
Taiwan on Monday morning, so I'm busy and forgetful at the same time...
