Comments on: Metamath html revamped http://pdf23ds.net/2009/03/11/metamath-html-revamped/ I will not be swayed be every small current; nor will the memes faze me or infect me. I am pure. I am intelligent. I am rational. I am at peace.

So if a hypothesis has child hypotheses that are expanded, they will be hidden. I have it do this because otherwise you'd extra lines between the hypotheses of the highlighted step that put them further away from each other and make it hard to read the substitutions being applied.

For longer ones however I have a trouble figuring out what happens when I click on that magnifying glass. When the glass is yellow I clicking on it hides some lines. When it is white and I click on it sometimes I see more lines of proof, sometimes less. What is the rule here? What is the "semantics" of clicking on the magnifying glass when it is white? It took me some time to notice that magnifying glass. I kept looking only because I knew something must be here to click. It would be helpful if you put some small "click on the [magnifying glass symbol] to see substitutions" or something like that. Also, typically when I look at a theorem I expect hypotheses, assertion and the proof. Here I can see only the hypotheses and the proof. I guess the assertion is kind of redundant for Metamath, since it is in the last line of the proof. However, it would be better to shows it just like the original Metamath presentation does.
