My ideas:
SEND button as an image (back end change will probadly be the best option).
---
captcha image - i would like to change background color of captcha image.
---
Those list with COLOR and SIZE options should be editable by css (for background, border, etc.).
---
Also NOTIFY EMAIL list got .inputbox class witch is the same like in many templates css and the templates ccs are readed first so if u wana change it u must change .inputbox in u main template. But what if u want get difrent look of .inputbox in u template and difrent in joomlacomment ?
---
Merge joomla READ MORE link with WRITE COMMENT would be nice. Like READ MORE (13 COMMENTS) or something like it (also option with image - hmmm like XXX[image-readmore]YYY[comments-normaltext].
Or even numeric characters as an images ^^ Well there is always something to work with
I can't wait for native 1.5.x version (beta) and i hope my edited css file will work with native 1.5.x version without any problems.
