Interface to create exchange rate

[davidmef]

When I was updating an exchange rate in Tricky Tripper 1.5.5 from F-Droid, I was a bit confused by the interface. I wanted to set it as 1 GBP = 0,8667 EUR as my bank statement showed.
The interface is:

field1
>>
GBP Rate EUR
<<
field2
Description
field3

I doubted and finally wrote 0,8667 in the field2 which is the right place. But I was confused by the >> << characters.
Maybe a better interface is:

field1 GBP
=
field2 EUR
Description
field3

or some other layout that makes clear what each field means.

In any case, thanks for the program and for making it open source.
