I display many informations in a manual slideshow (everytime I have forgotten how the name of that little church was...

1. I display the EXIF altitude.
I would like to add a "m" for meter, but if there is no altitude the single "m" is very useless/disturbing.
Best would be to choose the format (as for the date) for example "[0,0 m]" or "[00,00 Meter]" or "[0 meter above sealevel]".
This would also avoid the senseless decimals which are displayed now ("78.00000 m").
2. As I display several informations in a row I separate them with an "-" ("Germany - Berlin - Berlin").
But if there is a information not present it looks not good: "Germany - - Berlin".
It would be perfect to add logical operators for example: IF {IPTC:state} <> "" THEN "- " & {IPTC:state}
or to hide the explanation "IF {IPTC:country} <> "" THEN "Country=" & {IPTC:county}.
3. Formatting would be great: color for every line or even better change color tags ({red} {IPTC:country} {green} {IPTC:state} {RGB:0000FF} {IPTC:city}
perhaps also the possibility for simple format tags like {center} {left} ... {bold} [italic} {normal}...
Just ideas... Thanx.
