in RStudio Cloud, with an open script, I use F1 to get help on a function defined in a package which hasn't been loaded (
flag_integer in the example below):
The help pane pops up on the right, showing a helpful list of possible packages. If I click on any of these, I'm redirected to a 127.0.0.1 (the localhost page), which refuses to connect:
Not a big deal (I just need to load the required package, in order to access the right help page), but you may consider fixing it in the final release.
