The IDLE debugger has subwindows to display name-object bindings for locals and (optionally) globals. They have a gray background. Text is black, object strings get a white background box. The issue is that the white box and text for each name is slightly raised relative to the name. This is somehow especially noticeable to me for something like 'd = 3', resulting in
with 3 boxed and raised a bit so it almost looks like a superscript.

This is a fairly minor issue, so low priority now unless trivially fixed. But it should be part of polishing IDLE. I am hoping that this is not a tk bug that is terrible to work around.

With more debugger use experience, I decided that there are many possible small improvements that would make it easier to use for beginners.

0. The window strikes me as overall 'blah', if not ugly. The difference between inactive and active could be brighter.

1. There are 5 action buttons: They could be labelled as such, and maybe spaced out a big.  They could all use an explanatory popup.  [quit], for instance, means quit the current session *without* closing the window.

2. There are 4 display checkboxes. They could be labelled as such on a line under the action buttons. The buttons could then be spread out a bit.

3. In the middle of the gray field, I see, for instance, <module>0  # or
  <pyshell#0>:1 <module>0  # if enter statement interactively
'' is the file name, either 0 or 1 or both are line numbers (Python 0, tk 1). <module> seems redundant here as nothing else can be run,  unless importing another module in an open window would 

4. The first line in the Stack box (not labelled, unlike Locals and Globals boxes), always has 
'bdb'.run(), line 431: exec(cmd, globals, locals)
This seems like noise, better suppressed if possible. Next line:
>'__main__'.<module>0, line 1: pass

5. If one only has [locals], globals == module-level locals is displayed in a 'locals' box. If one hits [globals], that box is relabeled 'globals' and an empty 'locals' box open above.  Perhaps the initial box should be 'globals/locals' and relabeled to either when stepping into a class or function.

6. The offset with my current screen is two pixels, as determined by ___='______' and not as bad as I remember it.  Probably due to padding differences.

7. The font and fontsize of Debug Control are fixed, as with dialogs.

Have attached, implementing a ttk-based mockup of one possible redesign of the debugger UI, as seen in
msg251360 - (view) Author: Mark Roseman (markroseman) * Date: 2015-09-22 23:34
Have attached debugger-ui.patch, which greatly updates the user interface for the existing debugger.  

This also relies on some images that should be downloaded and unpacked into the 'Icons' directory:

Summary of changes:
 * works with both Tk 8.4 and 8.5+
 * paned window separates left and right, allowing adjusting relative sizes
 * on left, toolbar with graphical/text buttons, plus message, and stack
 * on right, local and global variables of selected stack frame
 * running program can be interrupted via 'stop' button
 * stack and variables use listbox (8.4) or tree (with resizable columns)
 * removed locals, globals, and stack 'view' options
 * source option changed to auto-open windows to see source
 * can always view source by double-clicking or context menu in stack
 * full value of variable can be seen via tooltip in variable list
In future, this will also replace the 'stack viewer' feature for displaying
exceptions, but this has not yet been integrated.

Mark, do you mind to rebase your patch to the latest version?
msg294128 - (view) Author: Louie Lu (louielu) * Date: 2017-05-22 08:11
Rebase markroseman patch to latest version, I own no credit on this patch.

Just want to check the effect about the patch.

Mark, Python now uses git and pull requests.  Can you, and do you wish to, rebase and convert to a pull request, any of your patches we wish to investigate further, yourself, or should we go ahead and do so?  Silence for a week will be taken as the latter.  The main difference is being the author of the pull request, versus 'merely' being credited in the commit message, as before.
msg294175 - (view) Author: Mark Roseman (markroseman) * Date: 2017-05-22 19:54
Please go ahead with any of the patches I submitted earlier, credit is absolutely not an issue.
msg305008 - (view) Author: Terry J. Reedy (terry.reedy) * (Python committer) Date: 2017-10-25 20:12
IDLE now uses ttk unconditionally by requiring tk 8.5.  The patch can therefore be simplified accordingly.

have updated/cleaned up the previous patch, and there's a new PR. i realize this is unfortunately a somewhat monolithic change which might make reviewing it a bit tough...
