UX: /admin/logs pages are not easy to use
I was trying to track down an issue with missing emails from our githost.io instance, and I've found that the log viewing screens at /admin/logs are really quite tricky to use.
It'd suggest the following might be ways to make the page easier to use:
An easy way to get hold of all the viewable log entries; either a 'copy to clipboard' button, or a 'download to file' button.
It would be useful to be able to see older log entries somehow, currently I can only investigate issues if I do so within about an hour, after that I can't access the older log entries. A download button that grabs the whole file (and if the logs are cycled, perhaps the previous file too.)
production.log doesn't have timestamp prefixes on the line (it has date suffixes, but only on lines at the start of a HTTP request), which makes it harder to find the relevant entries
The use of a scrolling area within a page that is also scrollable makes it hard to scroll the area that actually has the log lines. Often when I try and scroll a long way the log lines scroll for a little bit, then they stop scrolling and the main window scrolls instead. One way to avoid this would be to avoid the inner scroll area - simply make the page as tall as is necessary to accommodate all the log messages. (Seen in up to date Safari on OS X El Capitan, scrolling using tracking two finger dragging/flicking. It seems to happen most often when trying to scroll up from the very bottom of the logs.)
As an enhancement, an option to filter the logs, showing only lines that match particular strings would be nice, but not really essential if 1 & 2 were implemented.
