I am eagerly waiting on this change, whats like the time frame to get this PR merged and what part of the release this will go into ?

[mickael-menu]

@mrifni For a release we'll have to wait a few more weeks, there's also the new audiobook navigator to merge in before. But we could merge this in develop pretty quickly. Would you be able to test from develop?

We're integrating these changes at my company this week, so I'll make sure everything works well before merging in develop.

Btw not to get your hopes up too high, the current implementation finds search results and opens the publication at the right position. But the search results are not highlighted in the navigator. This will need a separate "decorator" feature which will come later. This is my next subject.

[mrifni]

sure, I can test it. Highlight fix is my next big expectations :)

[mrifni]

any idea when this would be merged and be part of a release?
