How/where do I upload my .blend file comes up all the time. I suggest adding a button/link to http://blend-exchange.giantcowfilms.com/ for uploading a .blend file above the text box with the other options like B, Italic, Hyperlink, etc...

• There are probably technical limitations at play here, not sure the editor toolbar is modifiable on a per-site basis, but I 'd vote for this yes. Along with a button to insert the <kbd> formatting tags – Duarte Farrajota Ramos Mod Aug 4 '17 at 18:57
• Note that blend exchange is not part of this site, but was created and is run very generously by a user : @giantcowfilms. – user1853 Aug 5 '17 at 1:51
• @DuarteFarrajotaRamos We have a user script for a <kbd> button, in case you weren't already aware of it. – gandalf3 Mod Aug 7 '17 at 20:56
• There's also a user script which adds a blend-exchange button. – gandalf3 Mod Aug 7 '17 at 21:37
• I use Vivaldi Browser which has a nice Insert Note feature, one of which is this keyboard markup, which I use to insert that snippet, but a userscripts sound pretty neat too. Definitely gonna check those out. – Duarte Farrajota Ramos Mod Aug 7 '17 at 22:30

I think this is a great idea, but we'll need to get SE to add this. We don't have control over much of the help center content.

I propose adding something like this at the end of the "how to ask" page:

If your question involves troubleshooting strange behavior, the fastest and simplest way of finding the answer is often by providing a blendfile and/or screenshots for others to examine.

And something like this to the ask question page (à la codegolf):

• Hm, I just noticed the question was mainly about the buttons directly above the textbox, not the help on the side.. I don't think there's much chance of getting anything official in the textbox buttons (we've tried before, but we haven't even got an official <kbd> button). However we might be able to get text added to the help/ask question sidebar, which IMO would be the next best thing. – gandalf3 Mod Aug 7 '17 at 21:28
