I have mentioned this issue several months ago and I wish it gets fixed.
When I do a code foramt in an aspx page, I sometimes lose the bookmarks in the page and the page scrolls to the top of the page after the code formatting. It seems this happens after doing a certain amount of page changes like adding or deleting some lines of html.
If I have a bookmark on a line that reads something like <div id="someid"...> and I do a code format, why can't R# find that line again and assign the same bookmark on it? I know the line # changes after the code format but so what? Just find that line again.
This issue happens frequently for me to be annoying. I have to find that line by manually doing a find and using a keyword which I have to jog my memory to extract.
