Hello, I start to make a child-template for persona. The modifications will be light as some style change, add widget zones for categories, etc. I also would like to use a svg as logo and i would like to respect the flexibility and the back office structure. As i begin, i would like to know, is it possible to add field into settings page from the template? For my example, i would like to add an additionnal upload field into the general settings page? One for the svg, the other one for the png fallback. Another idea, add a check box for a no index option? Maybe i have to creat a plugin, maybe it is an option in headers on the advance settings page (i don't understand what is it about?). Thank you in advance for any help. jB
