* Google Translator issue, <http://forum.textdrive.com/viewtopic.php?pid=128393#p128393>

* Web server requirement still appropriate?

* No errors when using the compressed code without debug!

* No communication if Flash is off-screen? <http://discuss.joyent.com/viewtopic.php?pid=180397#p180397>

### Flash Refactoring ###

* Set anti-alias to "text" in .fla, don't that after that?

### Linux ###

* No Flash <--> JavaScript communication in Konqueror. See also <http://bugs.kde.org/show_bug.cgi?id=154282>
* Still no transparency support :(

### Opera ###

* Detect User Style Mode?

### Firefox ###

* overflow:hidden; seems to have very negative CPU usage side effects in (at least) Firefox. Is fixFocus affected, as well?
* Problem with fixFocus? <http://discuss.joyent.com/viewtopic.php?pid=172679#p172679>
* fixFocus required in FF3?
* fixFocus movies can be scrolled using the scroll wheel, <http://discuss.joyent.com/viewtopic.php?pid=173099#p173099>
* selectable:false is broken on FF3 / Win.

### WebKit ###

* Scaling is inaccurate, no resizeAfterScale?
* XHTML support broke, probably because of pre-fetch, see <http://discuss.joyent.com/viewtopic.php?pid=178937#p178937>
* Resizing text with replaced <script> tags gives trouble, see <http://discuss.joyent.com/viewtopic.php?pid=181846#p181846>

### IE ###

* font-size specified in CSS in pixels? leading is not taking into account in the height guestimate.
* sIFR#calculate, IE?
* sIFR & ARIA? (Firefox, too)
* IE8? <http://discuss.joyent.com/viewtopic.php?pid=175062#p175062> (see mail, too)
* IE: use onresizeend event?
* Can't blur movies focused by click, or simply by hovering opaque/transparent movies. Either find a way to do so anyway, or perhaps try and scroll the Flash movie away from the cursor. See also <http://discuss.joyent.com/viewtopic.php?pid=172927#p172927>, <http://discuss.joyent.com/viewtopic.php?pid=177300#p177300>, <http://mediavrog.net/blog/2008/04/28/javascript/sifr-probleme-beim-scrollen-im-internet-explorer-6-und-7/>
  * Perhaps use tabindex=-1 and then focus?
* @import differences? <http://novemberborn.net/sifr3/beta2#c001160>
* Return of the mirror bug? See Mike Reid's mail.
* Triple XXX: <http://discuss.joyent.com/viewtopic.php?pid=179844#p179844>
* replaceText() in IE6: <http://discuss.joyent.com/viewtopic.php?pid=181949#p181949>

### Debug

* Only validate each unique source once
* Validate selectors (count 'em)
* Add XHR-based source validation debug option thingy
* Ratio calculation should work with just the Flash source. <http://forum.textdrive.com/viewtopic.php?pid=139411#p139411>

## RC

* Speed improvements
  * <http://ajaxian.com/archives/benchmark-prototype-and-jquery>, <http://www.jackslocum.com/blog/2007/01/11/domquery-css-selector-basic-xpath-implementation-with-benchmarks/>, dojo css parser, <http://ejohn.org/blog/getelementsbyclassname-speed-comparison/>
  * <http://blog.stevenlevithan.com/archives/faster-trim-javascript>
  * parseSelector should stop parsing when `select()` returns an empty list.

## After 3.0 ##

* Can effects from <http://www.swfir.com/> be used?

## Add-on Ideas ##

* sIFR and broken Flash players
  - Use sIFR.onReplacementStart event
  - wait for ping, if not within X seconds (customizable) undo sIFR
  - (rollback)
  - sIFR.onbrokenflash() event to notify user
