It may be that I need glasses, but as of late it seems to be the text is a tad bit smaller then I'm comfortabel with. Is it possible for Ag 3.0 to make it possible so that, I can select how big the font is?
I'm not suggesting that I be able to choose what size font I type in, but that, I can choose to view the text is zise 14, 16, what ever. Not sure if this is possible, but might be nice.
There isn't a need for that as you can easily change font size via your browser's settings. Well, hopefully you can do so with your browser. Zooming also works.
If you have a scroll wheel on your mouse, you can also hold CTRL and scroll the mouse wheel up for bigger text, or down for smaller text. And, as ExboMarker said, Ctrl-Zero will reset it to the site's default setting.
