You have to wait for the large asset icon to load before you can safely begin editing a form in WebGUI. This is due to the fact that the image size isn't in the image tag and the form scoots down after the image loads.
Please consider adding the image size to the image tag so that the form doesn't move during the render.
This would involve changes to AdminConsole->render and the AdminConsole templates.
Respectfully, but you're wrong.
Not everyone uses the inline editors, and this RFE specifically addresses rendering versus download time.
First, some facts:
1) Not everyone uses the inline editors
2) Not all forms have HTMLareas
3) The speed of rendering is how long it takes the browser to orient and size all elements of a page. Once everything is locked down, then you can start to fill in forms, even before all graphics and other (unrelated) javascript have been downloaded.
Now for subjective stuff:
This RFE is very narrowly defined and simple to implement to increase the likelihood that it will be accepted. I've watched several different RFEs and have noticed that vague or poorly defined RFEs don't get lots of karma, no matter how good the ideas might be.
Your idea may have merit. I would encourage you to submit it as its own RFE.
And to add to Colin's excellent points:
a) Piggybacking your own ideas onto someone elses RFE is at best poor taste, and at worst tends to muddy the original concept. It's one thing to discuss the original idea, it's quite another to add on your own wants/needs into an existing RFE.
b) For people using the WRE, implementing that gzip solution won't actually gain them any performance, because the WRE gzips all text content as it sends it to the browser anyway.
If you still insist on seeing this RFE be implemented, then please create your own post.
