Just thought i'd throw in my 2 cents.. I love this app! even without using widgets, having a sense ui slider on my Froyo rom is amazing. Add the ability to have my music, teslaled and some other widget and I am happy.
As you guys can tell by him responding to this thread, the dev is great. I emailed him a while back with some bugs and feature requests and I'm pretty sure he's added/fixed everything I asked for.
It doesn't slow the phone down at all and works well with LauncherPro and QuickDesk.
That being said, here's my new set of feature requests

:
Small things:
-Add an option to change the date format on the Sense UI slider.
-Add AM/PM to the time on the Sense UI slider
-Move the date on the Sense UI slider down a few pixels so it's fully on the little black band as opposed to partially on the band and partially on the grey slider (I explained that poorly lol,
this picture says what I mean, put the date in that spot)
-Make the Sense slider a little more "snappy" or something. I don't know how to explain this, but on a real Sense phone, you can just fling/throw the bar down and it unlocks as opposed to fully dragging it down. WL gets the slightest bit laggy for about half a second if you throw it down like that. I know, I'm nitpicking. Sorry

-
Is this possible?
-Can you add... a SLIGHT shadow or
something to the numbers that make up the time? They don't seem totally crisp or something, sort of like an image that has a resolution that's slightly too low. Or am I just seeing things?
^as you can probably tell, I love having Sense on my Moto Droid and want to make it perfect. and yes, I'm a wee bit of a perfectionist
Bigger things:
-Make an option to have 2 or more screens to slide between. I'm pretty sure FlyScreen offers something like this.
-I was reading through the beginning of this thread and I saw that you suggested that it might be possible to replace the slide to vibrate/silent with slide to unlock homescreen widgets? Would that be doable? (I didn't read through the whole thread so sorry if that's been answered). And if it is and you can implement it on the normal Android slider, would it be doable on the Sense one as well (i.e. drag it up about half an inch or so to unlock/lock widgets)
-I have an idea. I don't know how well I can explain it, but I'll try. I personally use WL for my music controls, but I'm not always listening to music and I don't always need them cluttering up my beautiful lock screen. Would it be possible to make a certain widget "hide-able" when the user does something like holds the back button, double taps the menu button, triple taps the widget, or something like that?
I'm trying to think of more ideas but I think I'm out for now haha.
I'm not developer so I don't know how relevant my ideas are or if they're possible, but I figured it can't hurt to throw them out there.
I've already recommended WL to a few of my friends with Android devices and they tell me they love it, and I do too so I hope you like my suggestions dancedroid
Oh, and what do you know. I checked the Market after typing this post and there's an update for WidgetLocker

You're one of my favorite devs.
editz:
OK, got that. But on the other sliders one slide turns the sound off. The Sense one doesn't do that, then?
Correct. The actual Sense UI keyguard doesn't have a sound on/off toggle. I tried to think of a way of adding it in there but didn't have any ideas of where/how to do so. I'm open to suggestions.
Like I suggested for the lock/unlock, sliding up a quarter or half inch could control sound? Don't know if this is feasible though.
One more thing, I have cheat mode enabled for whatever reason and I couldn't help but notice that there are two different numbers in milliseconds.. what's the seconds one?
And I'm always open for beta testing if you need it.
