On the page com/wp-travel-cart/ there is a place to add taxes and I can customize the tax amount in settings.
What I would like to know is if it is possible to modify the word “tax” to something like “convenience fee” to charge a percentage fee for paying by credit card?
“Tax” actually is a general term so it is added instead of any other string. Also, keeping in mind that some users might want to rename it to some other name that is why we have coded in such way that it could be easily renamed through the use of child theme.
As for the admin section as mentioned above, we will definitely work on it in a future update.
If you have any query/confusion further then please let us know.
