First off, I would like to congratulate you on the latest update. I was actually on the verge of uninstalling Sidewise right before that happened, due to the large amount of glitches I kept experiencing, which I reckon was partly due to my way of using Chrome. So far it seems to be working fine, but there are still quite a lot of things which would make Sidewise a much better tool.
I use Chrome very extensively, and in a way probably only a very low percentage of people do. Sidewise helped quite a bit, but there are still a few things that hinder my workflow. Namely, the issues with multiple windows. I find that Sidewise doesn't handle multiple windows in a very efficient way.
Firstly, having several windows—hibernated or not—causes Sidewise to become rather cluttered. I was happy to realize that I can change the CSS to my liking, and came up with the following, by reducing overall sizes, and more so on the hibernated windows (they don't really need to be big as they are rarely accessed): http://i.imgur.com/07ZW5.png
Though this usually a matter of preference, I prefer a more compact UI as it provides me with a broader view on everything. Obviously for a maximum of around 10-15 tabs (which is what most people use), a more 'comfortable'-sized UI would look better. Being able to trigger between a compact or comfortable UI would be a good idea, similar to the GMail UI.
Now, the biggest problem with having multiple windows is getting back to Chrome from a different application. One way to do it is to click on the Sidewise window first, and then choose the desired tab. This isn't the best solution as it involves multiple actions, as well as having to sift through the entire list of windows and tabs. Using the previous screenshot as an example: to get back to my last active tab on the second window, I would either have to click the window itself on the taskbar, or find it in Sidewise (which would be rather hard, because Sidewise doesn't show the actual active tab on each window, just the last active tab). I usually end up sifting through my Chrome windows, trying to find the right window so I can find the tab I'm looking for, which is a slow process. One thing I would love to have which would help a lot with this is to rename the title of each Chrome window to the title they possess in Sidewise, rather than using the active tab as its name. This would make changing between Chrome and other applications much easier.
Now for the biggest issue I have with Sidewise... When switching between Chrome and other applications, if I click on a window which is not the main Chrome window, then Sidewise will not pop up. This is obviously quite irritating and usually ends up with me using the normal Chrome tabs because making Sidewise pop up would involve more clicks than needed. I assume the reason this isn't fixed is because of Chrome's limited API.
One way I thought of solving this is to make a Windows Application which will scan the topmost window periodically; if the window is a Chrome window (other than Sidewise), bring the Sidewise window to the front. I am pretty sure that would work, and am actually going to proceed to code that program after finishing this post. Using an external program is obviously not the best solution to this, but quite honestly in my opinion it doesn't really matter as long as the desired result is achieved. As for security issues, I could simply make the program opensource and put it on github. I will keep you up to date with how this goes.
