RE: If translating labels is not an option in the CMap template, could I substitute text with icons (for open map, close map and bio)?
Translation of these labels are 100% possible. You can use your desired method of creating translations. I recommend using either POedit or the Loco Translate plugin. Any translations that you create, if you could send me the PO files, I will distribute them with the template in updates.
RE: To solve the category localization issue, how easy would it be to copy the original directory, making the necessary amendments for the next language?
Well, I suppose you could use the CSV Export tool found on the Connections : Tools admin page under the Export tab. You would want to use the Export All tool at the bottom.
You could then make all your changes, including the translated category names. IMPORTANT, you would have to remove the Entry ID column. If you do not remove that column, then the changes would be applied to the original entries.
Then you could import the updated file using the CSV Import extension.
Hope this helps!
