I'd agree with only some of the suggestions.<p>> <i>[all things color scheme]</i><p>A decent color scheme is enough. People don't change it much, if at all, unless they're bored, so I wouldn't go out of my way to support it. Main use cases are, arguably, light and dark mode, and supporting an OS-global switch if one exists. Tips about assigning colors to things are spot-on, though; consistency and discernibility turns color into a powerful communication tool.<p>> <i>WYSIWYG editor that behaves like Word</i><p>Yes please. In some ways, I'm sad that ActiveX/whatever the way to embed Word on your webpage was died. People really shouldn't keep reinventing their own WYSIWYGs on pages, each with slightly different behavior or interface. That said, this would probably be handled best by a set of guidelines or a library from Microsoft, instead of having to connect to actual Word.<p>> <i>Number/date formatting to the right locale</i><p>In my personal opinion, locales should die, and everyone should switch to dot as decimal separator and ISO-8601, respectively. But I'm fully aware the general consensus seem to be different :/.<p>> <i>Tell me what this does before I click on it</i><p>That's what tooltips are for. Harder on mobile, but there's no excuse for web developers who don't include them.<p>> <i>Support touch gestures and mouse</i><p>Support touch gestures <i>and</i> mouse <i>and</i> a stylus, simultaneously, as separate things. Because they are separate. A pen/stylus on a 2-in-one computer (e.g. Microsoft Surface or Dell Latitude lines) is a huge productivity booster <i>if it's supported</i>. It rarely is. I'm constantly hunting for software that does it right, but there's very little of it, and I have not yet seen a single web application capable of handling a stylus (even though technically, the APIs for that are there).<p>Examples of correctly handling a pen vs. other modalities: without having to switch modes or active tools, allow me to draw with a pen, select with one finger, pan with two fingers, and select with a mouse.<p>> <i>UX</i><p>The entire section is spot-on.
