MRG - MeRGed (code from a branch or a patch)
Status:
-> 2005-02-02: Features for 3.4 done. Ready for bugfixes.
-> 2005-01-27: Stable and leakchecked. Usability: needs testing.
-> 2005-01-20: Stable. Apart from a bad (but still safe) memory deallocation
mechanism the core is ready for a public release.
In progress 3.4 features (deadline is 2k5-Feb-2):
-> new word highlighting for searches / other highlights
More items (first items will enter 'In progress list' first):
-> go to next/previous bookmark actions (showing in thumbnailslist rmb popup too)
-> viewport restoring: sometimes it seems to restore the viewport a bit under where it was
-> viewport restoring: save the page width setting between runs (save/restore zoom factor)
-> presentation: provide a pageX/totalPages indicator in addition to the circle one
-> add scrollbar marks for bookmarks (like kate)
-> google search in the page
-> search: google search in the page
-> cleanup code and update README.png
-> find-as-you-type: use shortcut for 'find next' action (not the default one)
-> search: use shortcut for 'find next' action (not the default one) in find-ahead
-> show Viewport in ThumbnailsList (blended/contour)
-> Delay TOC (DocumentSynapsis) generation (and move it on thread)
-> refactor ThumbnailsList to do internal rendering as pageview does (way faster
@ -79,6 +77,7 @@ More items (first items will enter 'In progress list' first):
-> export: export to other formats keeping formatting (a dream.. except for PNG :-) (PS is easy, we just have PSOutputDev that does it :-D)
Done (newest features come first):
-> FIX: memleaks, bugfixes (1,..)
-> CHG: changes and cleanups in pageView's mouse handling functions
-> ADD: KTTSD simple support: speech selection using kspeech api via pure dcop (don't break compatibiltiy)
-> CHG: right click and drag while in 'normal' mode changes to 'selection' mode and selects
