Reload barely means "replace the buffer with the current file's
content", it's not connected to the undo history. And it still does that.
You can disable that feature. What's your problem?

So you are concerned about very large files. I understand that. But
that's really an edge case, and I don't feel that everybody else should
suffer for edge cases. Especially not because Geany is an designed to be
an editor, not a very-large-file viewer.
The various preferences are exactly for that, to make up for such edge
BTW, I think we only store the undo on reload if the file has actually
changed since it was opened. So for simply viewing dumps there shouldn't
be an increased memory footprint:
/* We only add an undo-reload action if the document
has actually changed.
* At the time of writing, this condition is moot
* generates an undo action even when the text hasn't
really changed, so
* actions_count is always greater than zero. In the
future this might change.
* It's arguable whether we should add an undo-reload
* especially since it's possible (if unlikely) that
there had only
* been "invisible" changes to the document, such as
changes in encoding and
* EOL mode, but for the time being that's how we roll. */

The feature was targeted at 1.25 already. The feature itself hasn't
changed (you didn't do anything to optimize it either). We simply
created a UI to inform about it. It wasn't rushed either. The PR was
open for more than two weeks and was ignored.
