Behaviour of Show Original

[nclm]

For now it seems that Show Original does it for like one second after clicking and then goes back to normal. It would feel more natural I believe if either:

• It would switch only when pressed, and revert on release
• It would switch when click, having the icon changed/highlighted, then revert when clicked again

Thanks for making all of these issues ^^

All of them are features/enhancements I've been planning to implement and it's nice to have them written down haha
