I took a screenshot: https://i.imgur.com/tdCGcqS.png

I've used it in the past, and it is quite decent.

What are the puzzle pieces at the top for?

Reminds me of a similar looking UI contraption I saw recently: https://staticdelivery.nexusmods.com/mods/1704/images/921/92... (the multicolored database icons at the top)

Quickly-running plugins. I haven't used them, but it seems like a important aspect of the editor. Here's the plugin preferences window: https://i.imgur.com/HAtJ5ej.png

Thank you, I was trying to figure out if it was a WYSIWYG editor or what.

It appears to be largely equivalent to the Calibre editor.

It doesn't look that different, at a glance, than the e-book editor included in Calibre.

"When I said I couldn’t work as the sole developer of Sigil people went overboard and acted like the sky was falling. Kovid Goyal from calibre stepped in to create Sigil’s Spiritual Successor which is an EPUB editor as part of calibre."

There's far too many developers that seem entire unaware of the very basics of marketing or how to connect with a target audience that's not other developers.

Developers want screenshots. The only people who don't need a screenshot are the project contributors.

It's kinda funny how we will spend years collaborating on some project yet not think to spend 30 seconds checking a screenshot into the readme for a project that we supposedly want others to find and use. It's like self-sabotage.

I think it's because there's 10 things to work on at any time and adding a screenshot can be useful but the documentation will constantly change as the project is updated.

Then you finally feel like you're done but now there's 100 different things that you have to document and you get overwhelmed.

Personally, not sure I would trust my project, and my time and effort to software written by someone who won't see the value of adding a screenshot to their software's site.

It was started in 2009, and for some reason.. no screenshots.

For me, that breaks trust.

I also went to the web site looking for screenshots, but the "home" page is a detailed changelog. Oh, there's an "About" page, screenshots are probably there-- no, that's a life story of the project.

Neither of these are interesting for the (presumptive) target audience of "people who want to edit epub files".

I have the same frustration. Why would I download a GUI tool without knowing what he tool looks like?

these situations are so frustrating it almost feels like it was their malicious intent to cause you mental anguish sometimes. "hey, check out this gui tool that you need! not gonna show you what it's like though ;) you just gotta download it and set it up."

Same here. I ended up doing an image search:

While I'm not one to get overly angry about it, cause it just kinda happens with a lot of projects as well as with a lot of Linux apps, no screenshots on the distro repo GUI app for a lot of software I tend to agree. It would make a nice contribution to their GitHub, but their homepage should feature a screenshot or two on the side or somewhere immediately visible to someone visiting their website, or at the very minimal a 'Gallery' page.
