gedit Find/Replace

A quick design/UI review of find/replace in gedit.

Current State (3.14)

Find drop-down thingy:

Clear button/icon moves position as you type.
No visible way to close the drop down (not necessarily a bad thing, but worth noting).
There's no way to switch to the find/replace dialog, which you might well want to do after performing a search.

Replace dialog:

Dialog title should be "Find and Replace" (since that's the commonly recognised term, as is a more accurate description than replace on its own).
Find box is labelled "Search for" - which is inconsistent with "Find".
Doesn't show you how many matches there are. Doesn't allow you to navigate through matches. Inconsistent with the dropdown in these regards.
Text entry drop downs sometimes don't do anything (if there is no history). Wouldn't autocomplete be better?
Repetition of "Match" three times in the check boxes.
"Wrap around" checkbox is ambiguous.
Too much vertical padding between check boxes.
The position of the close button is awkward. Would be more consistent to make this a presentation dialog, with an "X" close button.
Why is there a find button? The drop down doesn't need one.
Button order - shouldn't it go Find, Replace, Replace All? (Since this is the order you will often use the commands.)
When the replace field is empty, Replace/Replace All will delete matching text. This isn't communicated though.
No obvious way to undo. Ctrl+Z doesn't work.

Design Ideas

Some ideas and suggestions.

Find Drop-Down

This is a minor evolution of the existing find drop-down. Differences from the current one include;

Clear button has been moved after the number of matches text, in order to keep it stable.
New button allows you to open the find/replace dialog directly.

Find/Replace Dialog

Another simple evolution from the existing UI. Changes:

Kill the drop-down history in favour of autocomplete.
Remove the Find button and do live matching.
Add next/previous buttons, and remove the search backwards preference.
When the replace entry field is empty, show a "Nothing" placeholder text, to communicate that the Replace and Replace All will delete the selected text.
Change the checkbox layout to use two columns, and save vertical space.
