MainWindow should have a MetricReporter that's installed as a permanent widget on the status bar, as opposed to labels that are each individually set up and permanently added to the status bar.

MetricReporter will own all the labels necessary for word/char/line/col reporting.

MetricReporter should also have its own update slots for each label. MainWindow will then simply interface between the current editor and the MetricReporter and won't have to care about updating those stats manually.

This should hopefully make the code in MainWindow a little cleaner and more compact, as it will delegate all that "management" business to a helper class that it will then own.

Brace matching does not work as intended. If a new brace is inserted between existing code blocks, then the algorithm effectively breaks and doesn't work as intended. Find a workaround.

For example, suppose the document is currently empty. We enter an opening brace, and the expectation is that a closing brace will automatically be inserted. This works as intended:

However, now let's suppose we already have an existing pair of braces like the ones above, and we try to insert an opening brace on line 1 (having moved the existing pair down a couple lines). This is what happens:

The brace-matching algorithm is a bit flawed. See handleKeyPress in Editor.cpp.

Word counting algorithm is a bit unclean and has some unnecessary lines.

It may also be useful to see the total number of lines on the status bar (as well as the current, though that's shown in the left-hand pane anyway).

The status bar should reflect what language is set for the current tab.

The screenshot showcasing syntax highlighting is outdated and needs to be updated. It's using an older version of the syntax highlighter that didn't properly pick up keywords.

Bug: When switching tabs, the current column count gets reset to 1 until the cursor actually changes position again.

Maybe cover these:

• Saving a file, basic syntax highlighting
• Replace-all and find operations
• Saving unsaved tabs before they're closed

It does not make sense for MainWindow to have a syntax highlighter. Rather, each tab/editor should have its own syntax highlighter. It should also manage the generation and garbage collection of syntax highlighters internally, without MainWindow having to worry about that logic.

All that MainWindow should do is:

1. Tell the Editor what language the user wants to set, if any.
2. On tab change, simply update the menu language option to reflect the new tab's option; don't worry about the highlighter.

For example, instead of constantly using TabbedEditor's widget method and casting the result to an Editor*, there should exist methods in TabbedEditor for retrieving tabs by index, retrieving the current tab, retrieving all tabs, and retrieving all unsaved tabs.
