At present deletion of a context requires the user to enter DELETE in the box. It would be better to get the user to enter the name of the context instead in the popup box. That way the user is actually confirming they are deleting the correct secret, rather than confirming they are deleting any secret.
I've just accidentally deleted the wrong context in our organisation. I think what happened was that I deleted a context and then immediately clicked the context below to delete that one too. I hadn't realised the UI was still updating and therefore my click actually took place on the one below (as rest were shifted up). I didn't spot that in the confirmation box and just entered DELETE anyway. Having to enter the name of the context I was deleting would have stopped this from happening.
