I have added a tab for subsp. and vars. which is intended to help standardise recording. Hopefully you will all be able to contribute to this - just click on the pen icon to go into edit mode. If there is no pen at the bottom of the post then you will need to log in first.
I also think a tab showing systematic list for the whole of South Wales with a column for each vice-county would be really cool. Sorry Sam, this would be down to you so something for if you ever feel inclined rather than a request.
If anyone has any other suggestions for additional tabs feel free to make suggestions.
