• "Close" doesn't always have the cross icon.
  
• "Cancel" doesn't always have the cross icon.
  
• "Clear" doesn't always have the cross icon.
  
• Many "Close" buttons are (natively) just "OK" with an arrow in Qt and some places (error messages), instead of a "Close" button.
  
• "Remove" is sometimes called "Delete".
  
• "UPDATE!" and "Download" may be different.
  
• "Add defaults" button may be aligned differently with the other buttons.
  
• Mixed capitalization.
  
• Password prompts may be missing the small "Clear" (?) button.
  
• Idgames URL being configurable (why?) but Wad-Archives URL not.
  
• "Copy to clipboard" and "Copy all to clipboard".
  
• Some settings being presented as questions (with a question mark) rather than... not.
  
• Different font typefaces and sizes used in "close" dialogs (Program Args. vs JSON library license).
  
• Using a cross icon in place of a minus icon, and vice versa.
  
• "Program arguments" window title not being prefixed with "Doomseeker -" (not pictured).
  
• "Doomseeker - Copy Text" being used as a window title (not pictured), with "JSON library license" text in the window itself. (Should be "Doomseeker – JSON library license" or simply "JSON library license".)
  
• The pencil icon in Doomseeker not matching the pencil icon used on the tracker (not pictured). 😀

• Different dialogs have inconsistent geometry. E.g. some widgets may be X-positioned at 9, some at 0, some at 1, etc.
  
• Buttons are not often of equal width – sometimes acceptable –, but worse is when they don't have equal padding (ignoring translations). E.g. compare btnUpdatesDiscard and btnUpdatesDownloadAndInstall in mainwindow.ui (or nearly any other example given here).

• Create Game dialog mocks QWizard horizontal rule badly. (Likely to be redesigned with 0003480, though.)

• Buttons without icons might be 23 pixels tall, with icons 24 pixels tall.

Target 1.3.3? Because of cleaning up inconsistent language (0003942) too.

Quote from Zalewa
The system applies the icon when the button is created by the Qt's button box, but some of those buttons are added manually by us and only share the same text with the button box's.

src/core/translations/ca_ES.ts:        <source>Cancel</source>
src/core/translations/ca_ES.ts:        <translation>Cancelar</translation>

Quote from Zalewa
but what do you mean with the X-positioning at 9 vs at 0?

$ grep -r "<x>0</x>" src/ | wc -l
101
$ grep -r "<x>1</x>" src/ | wc -l
21
$ grep -r "<x>9</x>" src/ | wc -l
0

Also removed the padding around the dockable widgets and the server list, making everything touch the borders of the window.

- 'D' icon will now appear on all "Default" buttons.

I'll assume this is a joke.

• Capitalization;
  
• The checkmark is inconsistent with another example of a red "Download" button found previously somewhere, or a standard button which looks like a green arrow pointing sideways saying "Update" (in the new IP2C window);
  
• This also has a warning triangle next to it, although it's not arguably a warning where such warning triangle is normally used (e.g. "This path doesn't exist.");
  
• Ending the "New updates are available:" and "Updates have been downloaded:" to colon punctuation may be inconsistent (e.g. compared to IP2C update dialogs).

Quote from Zalewa
There was an inconsistency with the red X also being used for the "Clear" buttons, but those buttons will now have the "edit-clear" icon or the broom icon.

Looking again at qt5-fusion-style-qdialogbuttonbox-reference.png, the capitalization is all over the place in Qt, so I should not bother about capitalization.
