I've used sigil a lot in the last week after having not used it at all for about a year. There seems to be a lot of improvements made over the last year so that it is more user-friendly while being more powerful than ever. For example, just allowing the user to rename a file without having to type in the file extension every time is a big help! So I just want thank all the people who have worked on this latest edition.
I noticed some behavior that might be a small bug: When you open an epub and make a minor change to the css sheet and do nothing else, then when you go to close the app, no window comes up to ask you if you want to save/discard the change. Sigil closes without saving the change. Shouldn't the warning window come up in these instances? I noticed this only with the css sheet.
I also have two feature requests:
1) Is it possible to add the option to search in "whole word" mode. For the time being I am using the fix offered by Timur of enclosing the search in boundary tags (\b) ... but it would be so much easier if there were a simple checkbox.
2) Is it possible to save to Sigil a list of most frequently used regex search terms and their associated replacement counterparts? Like maybe 10? Right now, if you use a complex regex formula, it quickly falls off the drop memu of the most recently used searches. It will do that easily within just a couple of minutes of editing an epub as newly used terms take their place. So if I open up Sigil the next day or even an hour later, I have to open up a separate notes application each time in order to be able to use some frequently used regex searches. I always have a hard time with regex, so I always have to keep notes of what works and I just can't reconstruct the searches from memory. It's like Greek to me!
