Sigil does something that no other editor I have ever used does: It works on a SET of documents (sections).
All needs to have many meanings. It all depends on context.
Count (informational), should count Current: the entire current tab (html, CSS, NCX, OPF) contents
or
Count All: All Text (HTML). No cursor start point, start at the first file in the Text section in the Book browser to the last file in the Text section.
I disagree that Search(& Replace) should ever wrap.
Instead of Wrap, have a tick: 'Start at First (file/line, depending on mode:current or All HTML)'. the default is start from
here
this adds some confusion as to what happens with the next file in the sequence (All HTML Mode).
The reason for using All rather than just repeating
Replace Next
is quantity
So let me toss an idea
An ALL repeat Limiter setting (default infinite).
Repeat: n occurrences on This Tab, Repeat n Tabs, Repeat n NEXT occurrences, Where n is a spin wheel count
