On an android tablet, can I get the full keyboard back in Str8ts?

Ok I'm going to put an option on the player
When I use Android with the default keyboard the numbers are not shown, you have to SHIFT to see them

When I go to archive of Str8ts and click on an older one, it changes to that one, but when I then click on printable version, what I see then is the Str8ts of the day

Excellent catch, thanks. I've just fixed it. Daily Str8ts version is now v2.13b, [CTRL]+[F5] if you don’t see that
