Digikam 0.9 - some remarks

Hello,

Nice to see improvements:

1. Tooltips sometimes are staying partially when scrolling in album
   view.

   Reproduce: Place cursor in lower part of view with tooltip above
   cursor and scroll down.

2. Navigation in panel and in IE

   With highly interactive C&T panel on the right using mouse in IE (on
   the left) for navigation is cumbersome.

3. Name in right panel navigation widget.

   In Album view with right panels opened is navigation widget and
   beside is file name. It is often truncated. Maybe move it below nav
   widget? One line cost isn't very high.

4. File name issues:

   a) "Name change" dialog (aka F2) shouldn't allow for changing file
      extension OR when changing name extension is should automatically
      (eventually with help of some auxiliary dialog) perform
      transformation of image eg. from JPEG into PNG.

      Dialog window could look like (ascii-art):

      New name:
      +-------------------+
      |pa123456           |.jpg
      +-------------------+

      With non-editable extension.

5. List of Tags in C&T panel and IE

   With big collections list of tags can grow really big. Also
   complexity of tags combinations can be increasing. In this
   circumstances it is hard to know which tags are associated with given
   picture.

   That could be fixed in two ways:

   a) Add one line with list of tags inside of Tags fieldset in C&T
      panel (above search field).

      Pro: most obvious place

      Con: in album view possible redundancy with visible tags in photo
      plates. But with C&T panel it is highly probable users will turn
      off additional info from album view.

   b) Introduce new field in status bar of IE.

      Pro: with increasing importance of tags in digiKam this is
      important information and probably deserves its own place always
      visible (as album name is visible in title bar).

      Con: currently visible info in status bar (name, position in
      album, zoom, dimensions) is purely "physical" while tags are
      "semantical". It may introduce some ambiguity.

6.
Reproducible crash when removing something (date, filename) from album view
in
digiKam configuration:

7. Selection of images

   C&T panel changed scenarios of selection of images.
   One click opening while previously comfortable now can be
   disturbing. Nav widget only partially solves the problem.

   Possible solutions:

   a) Completely avoid problem making C&T panel only visible in IE
      Placing it on the left side would also fix navigational problem
      from 4.
   b) Make album view two-click area (and/or configurable like
      Krusader).

This is relevant of image loading for histogram computation on right sidebar.
I will fix it to use a separate thread to load image.

I don't understand what you mean. Please explain me better.

I will take a look . Any user report to remove this navigation widget. Any
viewpoints about welcome.

Hum, I need more viewpoints about...

thanks for the crash report

Now you have navigational part on the left and C&T panel requiring high
mouse activity (switching focus, changing rating, etc.). When doing
documentation of album it demands from user constantly moving mouse
left-right-left across the screen.

I know, there are keyboard shortcuts but many (even majority) users are
I know will never use them, even when their life depends on it.

Navigational widget is good, even necessary at the moment due to
problems with selection of images.
