Lizard has a lot of bad connotations in the US.
Do a Google search for lizard slang to discover them. Quite a collection.
The problem with gecko, however, is that to most people in the U.S., that's just the TV mascot for the GEICO insurance company. The animal has been hijacked.
Why not just release it as Chameleon, version 5.0? Make it clear that it's not really an "update" to the old skin, but a new incarnation. Or maybe Phoenix, the creature who rises from the ashes of what came before.
Jim Morrison was known as 'The Lizard King' due to his obsession with lizards. After years of drinking and heavy drug use he had developed the belief that he was able to control lizards with the power of his mind - that he had indeed become their 'King'.
Just did a quick fiddle, and a few things jump out at me....
The skin doesn't appear to use theme images, and that's fine - there are plenty of other skins that do. But the Theme image box in the Explore view should be shut off.
Thumbnail sizing and layout is a confused mish-mash. All the skin really needs is Max page width. Get rid of the settings for Thumbnail columns and Aspect ratio.
Let the user set the thumbnail image bounds directly, instead of having the skin change that value in the background. If I set the size to be 300x300, that's the size I want the thumbnails to be! Stop trying to do me a "favor."
If the user wants 3:2 thumbs, he can enter whatever he wants - 240x160, 300x200, 450x300, etc. If he wants more thumbnails on each row, but the same size, he can change the max page width. And that, BTW, should be a spinner, rather than presenting a collection of fixed values - maybe 500px minimum, 3000px maximum. If monitors get bigger, you can always kick the upper limit up to 5000px, or whatever, in a new skin version.
The current approach just leads to confusion and frustration. Thumbnail image bounds are user-settable - the user doesn't want the skin to be constantly changing those settings.
And you can end up with seemingly contradictory values. For example, I manually changed the thumbnail bounds and also chose a wider maximum page width, and I ended up with an album with 5 columns of thumbnails. That's fine, but the settings still said "4 columns."
It's as if you've got settings for X, Y, and Z. Changing X triggers a change in Y and Z. Changing Y triggers a change in X and Z. Changing Z triggers a change in X and Y. This is never going to work predictably and consistently.
And of course, if the thumbnails are always fixed shape, there's no need for settings for the maximum and minimum aspect ratios - those come into play only when you're not using the fixed shape filter.
Well, I just don't want to mislead people, that they can simply use this skin for adding new folders to a Chameleon collection.
I wouldn't worry about that too much. It's sort of like the transition from Tiger 2 to Tiger 3 - the user needs to process all the subfolders, and the end result is going to be similar to what was there before, but not the same at all.
If you do decide to make this Chameleon v.5, you might want to build in a little routine to delete all occurrences of slides/whatever.html. Otherwise, lots of leftover files!
Which reminds me - the Pages > Make slide pages setting should be disabled.
