The interface is appalling – it is very difficult to find your way around, in particular trying the relevant files for download or trying to find descriptions of plugins is nigh on impossible.
This is not only my opinion – I have found others who share my views on this – hopefully, WordPress will take this on board and sort out the interface of this potentially fantastic resource soon.
Another strange issue I noticed is that although I pinged and trackbacked the repository post on the WordPress Development site, it still displays as having no pings or trackbacks. I thought it was an issue with trackbacks on my WordPress install but I checked on another site and my trackbacks are working fine. Again, hopefully, they’ll sort this soon too.
