<p>It would be convenient to show also summaries in object history and browse pages and highlight the kind of change, for example:</p>
<h2>on browse pages:</h2>
<h3>for nodes+ways+rels:</h3>
<p>amount of tags (useful for objects with lots of tags)</p>
<h3>for ways:</h3>
<p>amount of nodes</p>
<h3>for rels:</h3>
<p>amount of members (or nodes and ways and rels members)</p>
<h2>in history:</h2>
<h3>generally</h3>
<p>highlight the kind of action by formatting (similar to how it is already done for deleted objects in changesets):<br>
e.g. show new objects / tags bold (and or e.g. green)<br>
show deleted tags (that are in version n but not n+1) as strike through (and or red) in version n+1</p>
<h3>for nodes+ways+rels:</h3>
<p>amount of tags (useful for objects with lots of tags), separated into amount total+added+deleted (compared to previous version)</p>
<h3>for nodes:</h3>
<p>position changed?</p>
<h3>for ways:</h3>
<p>amount of nodes total,removed and added (compared to previous version)</p>
<h3>for rels:</h3>
<p>type changed (only displayed if yes, e.g. type changed from x to y)<br>
amount of node members total,removed and added (compared to previous version)<br>
amount of way members total,removed and added (compared to previous version)<br>
amount of role changes</p>
