[How to search for a specific file?]

Yeah, that's what I was doing. But not having a quick and intuitive search is very inconvenient. But well, thanks for the tip.

[How to search for a specific file?]

How do I search for a specific file in a way that it'll give me all the changesets that file was committed in?

On mercurial this is just a matter of searching for the file in the search box, but Plastic's Search seems to work in mysterious ways...

[Ignore DOES NOT work. (Unreal 4 content/developers folder)]

Yes, we're a paying customer. I'll send this issue at that e-mail as well.

I don't think there's an ignore list in the UE plugin, we add items to the ignore manually by opening the ignore.conf file because we have a ton of stuff to set up.

[Ignore DOES NOT work. (Unreal 4 content/developers folder)]

Our developers folder is completely ignored as you can see below. (It was at some point commited but has since been deleted from the repository)

My

This is our ignore file

But whenever I add something to it (yes we use Plastic's Unreal Plugin but the team commits through Plastic/Gluon):

Plastic is all like "Nah brah, let's commit dat"

Our lock rules even state that "PLEASE DON'T TRY TO LOCK FILES IN THIS FOLDER"

We've had A TON of issues with Plastic's Ignore. And this has been a major point of contempt; with my team pushing for us to go back to Git. So yeah, I don't even know how to defend you guys anymore.
What could be happening?

[Is it possible to remove a specific commit?]

I want to remove that commit from the branch, what is the best way to achieve that? 

Is Advanced > Delete Changeset safe enough?
