There are some Screenshots available on the KeePass web site but they don't really give you a good idea of what you actually get, IMHO.
As it's Free, I would strongly suggest you download it and try it out by making a few actual bono fido entries for, say 6 diffferent web sites or so. Just for your own reassurance initially, you could make these non-financial web sites.
Then have a real life play around with it to see how it works.
1. Opening the URL of one of the web sites with just a click.
2. Copying over a username with a 'right click and select' (which lasts for only 10 seconds in your memory cache and then disintegrates within the cache)
3. Similarly copying over a password (these also only similarly last for 10 seconds in memory cache)
