Show Dry-Run for any Replace or Replace All
Would anyone here find the following new feature for Sigil useful:
Add a "dry-run" mode for Find and Replace that would show the before and after results from a Regex Replace/Replace-All in a big table but not actually make any changes at all (or possibly wait until user says okay?). Maybe a simple Ctrl-Click on the Replace button to do the dry-run.
Imagine a table with two columns, the first showing a short context (3 to 5 words on each side of a match) for each match, and the second column showing the same short context with the replacement made. But no actual replacements are done ( or until the user okays it).
The number of words of context could be a user preference.
Effectively this would be a faster easier way of making a Checkpoint, doing the ReplaceAll, and comparing using File level highlighted diffs, and deciding whether to keep or revert to the Checkpoint all without Checkpointing at all.
Would this be a generally useful addition?
