* localStorage cache is faster than chrome.i18n.get
* TreeWalker is faster than tHTML for removing extraneous whitespace
* simple for() is faster than for-of with [...iterable]
We don't mention the G+ iframe on CWS stylable only when "Out of process iframes" feature is enabled which can be set manually via chrome://flags/#enable-site-per-process. It's still in development and is known to break some sites, which is why it's not enabled by default.
To prevent cross-page leaks we need to create/copy prefs and cachedStyles inside the background page context.
* storage.js is now used only in the background page
* messaging.js now contains less bg-specific methods and more common methods. Added saveStyleSafe, deleteStyleSafe which automatically invoke onRuntimeMessage of the current page or just handleUpdate/handleDelete when notify:false
* prefs.js with 'prefs' for background and UI pages: separate objects because a UI page may load before the background page and it can read prefs from localStorage/sync/defaults
Chrome doesn't garbage-collect (or even leaks) SVG <symbol> referenced via <use> so we'll embed the code directly on manage and popup pages where dozens/hundreds of svgs are displayed.
* restore the correct width of svg icons
* popup: use the standard formatting & SVG <symbol>
* popup .breadcrumbs hover highlight
* manage: black links, transitions; use <p> in #options; trim .homepage
* edit: move regexp tester info link to a template
* Now that our own pages retrieve the styles directly via getStylesSafe the only 0.001% of cases where code:false would be needed (the browser is starting up with some of the tabs showing our built-in pages like editor or manage) is not worth optimizing for.
* According to CSS4 @document specification the entire URL must match. Stylish-for-Chrome implemented it incorrectly since the very beginning. We detect styles that abuse the bug by finding the sections that would have been applied by Stylish but not by us as we follow the spec. Additionally we'll check for invalid regexps.
Popup:
* Enforce 200-800px range for the popup width option
Manage:
* faster search via cachedStyles.byId
* faster restoration of search results on history nav
* style name is clickable and opens the editor
* animated highlight of style element on update/add/save
* expandable extra applies-to targets
* remember scroll position on normal history navigation
* boz-sizing in #header, also in editor
* applies-to targets use structured markup
* get*Tab*, enableStyle and deleteStyle are promisified
Switched info to `i` and found a pretty nice external link icon imo. @tophf As for pixelation on the info icons, you mentioned maybe a lighter color would help. For all icons besides external links, I made them lighter with darker hovers. Besides a really high zoom, I never saw any issue to begin with, but let me know if they're alright. I also changed them to use their exact original dimensions, so maybe that helps.
The icons I used are from right here on Github. They're SVG, so there should't be reliability issues. Wanted to see how they'd look, and I really kinda like it. Thoughts?
Styles are listed before actions by default. Actions are listed before
styles if `popup.stylesFirst` is false. A control for the option is shown
in "Manage" if `popup.stylesFirstUI` is true.
