So you want to ignore all tags/branches older than, e.g. 1 year, or sort them by the time of the commit they are pointing to and only keep the most recent x refs?

You seem to use/know FileZilla. Could you please share a screenshot and explanation what's so exciting about it? Thanks in advance.

This was a bug and fixed in the latest intermediate build (Help | Check for Latest Build) 13182.

For Git it should be sufficient if the user's ~/.gitconfig contains configured proxy keys in the http or https sections.

Do you mean the "sashes" between different views?
