The only reason I drag and drop decals (from the Toolbox) is to get their AssetID (http://www.roblox.com/asset/?id=XXX)
After numerous cycles of this, it gets tedious, especially since I have to select the decal, mouse and copy the asset ID, then delete the decal. I just want the Decal ID, not this other stuff that really piles after numerous cycles. Please make it so I can just middle-click a decal to copy its AssetID
Not sure why this isn’t a thing already. It’s such a pain to subtract -1 rather than just copying an ID, or having to insert decals via the toolbox as you’ve said.
Why middle click? Why not just Right Click opens a tab with a ‘Get texture’ button on it?
It doesn’t have to be. Usually the ROBLOX Engineers cover the small details such as that. I’m sure they’d figure out something that everyone can be comfortable with.
We already have it kind of implemented:
Unfortunately that copies this link: http://t7.rbxcdn.com/6cfd0f26685598f4285477cf2e7f6916 instead of the asset ID.

You could try out my Chrome extension (if you use Chrome). It obviously doesn’t work in studio, but if you are willing to browse for decals on the website, my extension will probably be quite useful to you.

Middle Click doesn’t do anything and is faster. boom
Middle Click function is empty and is faster. boom
