Help! Where has Customise gone?

[SDTGisAnEvilWolefGenius]

I hid a thread (a TV one, to avoid spoilers) and now I can't find Customise, to unhide it.

Talk > chevron > in there

If you're on a desktop, it looks like this - as Swedish says, you need to click on the the chevron to open extra thingywotsits! Customise is at top/left.

Thank you both - you are stars!
