Create an image gallery in slideshow
I found some similar requests like this but no one says about having a slideshow gallery. It's not pretty when adding images in too many tabs. The images can be in one slideshow gallery so people can swipe left/right to see other images.
Currently an image covers the whole width. Instead let the user control the image's width and allow them to arrange in grid.
API Method: Add response/request headers section
In the api method you can only add the response body, but you cannot write anything about the response headers, we would like to set a title or a label above each one of them, so reader can differentiate between the headers and body of a response or a request.
Custom color for in-line code text
There's already a request for color themes for code blocks, but it would be helpful to have the ability to set a style for in-line code (command-shift-6). The default is black text with a grey background. It'd be nice to be able to adjust both the text and text background colors to something that is more noticeable.
Site Preview Image
Add the ability to customize the color or entire image that is previewed when sharing a gitbook documentation link.
Allow Lock the Page's content and Tags feature
I think we need a lock content feature because sometime I just want to read the page and click somewhere in the Pages and it accidently create a unexpected element. Additional, we need a tags feature to give it page's categories, easier to finding. Last, I would like a feature which would allow user can link pages together to a seri or a list of relation pages
Action to duplicate pages
Very useful, if you've many api methods to clone pages and change the parameters.
Search and replace
It would be very help to have a search and replace feature to update and/or sync terms all at once in an article. The ability to search and replace across multiple articles and books would make this feature even more useful. Another related feature that would be helpful is a dynamic glossary (similar to labels). So, you could have a glossary page with terms you specify, and have an insert term function in articles. This would allow you to change a term in the glossary and have it dynamically update the term across articles. Terms inserted into articles could also be links to that term in the glossary page.
Support for footers
Ability to include a footer at the bottom of every page. Links, copyrights, texts, you name it!
Landing page for a space
Can you implement a landing page for the organizations and spaces ? This feature gives a project all what it needs, like a landing page and it's space contents Landing page could be html, css, and js. User can put his own. I don't know if makdown support for landing page could help or not.
