HTML5 itself actually didn't fail on all these things, it's just the way people use it gave up some of these features to achieve different goals. 1) I've been practicing a rule that all the web content I make can all be downloaded fully by a single cmd+s save command and fully runnable locally. It's extremely easy to do, just unpopular. 2) HTML5 does not contain any spec for tools. If you think HTML5 doesn't have great tools then it's the community you should blame. Personally I just use a text editors and some helper functions for all my needs. But I agree there's no popular + good non-code tools. The only thing is that browser is much more bloated than flash runners, but at the same time you can say it's lighter than a 3kb binary cuz everyone has a browser installed on their device, but all flash download prompts legitimate or not all look like malware (speaking of which I'm curious how flash download prompts became such a phenomenon in phishing would appreciate some quick links).
