I much prefer the 0.2.0 design, so congratulations!
Do you have any plans to support tiling of tabbed windows? I tend to work a lot in the stylesheet--it would be good to have that and the target file (in split view) visible at the same time. Then using a "refresh" you could easily see the effects of the stylesheet changes.
By the way, at the moment I'm not sure how best to get changes in the stylesheet to take effect. Closing and opening a tab always works, but is not instant. Saving (when the stylesheet is active) sometimes works, but not always. Do we need a "refresh" option (F5)?
I like your VS type interface--VS 2008 is my epub editor at the moment, but I can see Sigil will soon replace it. The one thing holding me back at the moment is the lack of search & replace across files (Ctrl+Shift+H)--pretty please!
Some minor things:
How about Ctrl+F4 to close the active tab? I suppose would be part of a normal "Window" menu, so you can select the tabs, tile, cascade, etc using the keyboard (and/or mouse).
Also Find will not find "CHAPTER" in book view given the following partial html:
Code:
<body class="text sgc-1">
<div class="chapter" id="ch18">
<div class="chapterHead">
<h2 class="chapterNumber" id="calibre_pb_44"><span class="bold">CHAPTER 18</span></h2>
</div>
