Cool ideas, thanks for sharing! And honestly if there's confusion or room for improvement, it's not anyone's fault but mine
It's definitely true that different people use the site and tools in different ways – for example we found some creators never used the Dashboard (and some didn't even know it existed) and instead just click "add episode" every single time. Meanwhile, others never use "add episode" or "new series," and instead go the Dashboard every single time.
As for the click vs. hover, that was done for a couple usability reasons. You may remember that back in the day the lefthand menu items (comics, creators, etc.) had their own drop down menus too, which either opened on hover or click depending on how far back you go. The little icon menus on the right side also went through a few iterations, requiring either hovering or a click to open as well. Anyway, we simplified the lefthand side by flattening out the menu options and getting rid of ones that weren't being used much, and settled on click-to-open for the righthand icons. The contents may be less obvious and require that one extra click to see... but it makes using the menus (clicking rows, scrolling up and down on the list, etc.) easier to manage.
If it opened on hover but you moved your mouse slightly outside the menu it would disappear, leading to frustration or causing an accidental click on some other part of the page. This is particularly painful if you were scrolling the Reading List / Purchases in Your Comics or the latest notifications under Activity... only to have the whole thing disappear at the wrong time. If instead the menu appears when you click (versus hover), then you can scroll or move your mouse anywhere as quickly and carelessly as you like without worrying about it disappearing on you. The Publish menu (i.e. "upload cloud") is simply the same way for consistency, as it'd be a little weird if all of the icons required clicking except that one!
As we've said before (and you're probably tired of hearing), we've got a lot of things on our to do list... but I can give you a little sneak peek into what we're thinking for the next Dashboard update.
When we started out, the Dashboard was basically just a list of Series and Episodes. Since then we've added Stats, Support, Premium, Revenue, and now Ads... so it's getting a bit complicated. What we'd like to do is add a sort of "hub" or main overview, with summary info and easy ways to jump into each of those sections. You can imagine seeing basic stats, new supporters, and your latest comments or other activity updates in one place, with the option to drill down into the existing sections for more detail. Once we put something like that together, it may make sense to turn the Publish button (cloud icon) into a single click... which would take you directly the dashboard overview to get a snapshot of what's going on, add new episodes, and manage your life on Tapastic as a creator. None of that is set i stone yet... but we definitely recognize the current tools need to be streamlined and simplified now that there's so many... if nothing else so you don't get lost or miss things!
Anyway, hope that helps give you a little background into the "why" behind some of the Tapastic mysteries (tapasteries?)...
