Np. The ElvUI adaptation doesn't work so well with S&L, it's better to just do it manually that way. But that's a topic for the ElvUI Addonskins authors, not you. You may want to contact them about it.
It was a bit tricky to get some things figured out, but the functionality is basically the same as in Skada. I like that. The data seems to be more or less what I expected it to be, Damage Meters never have 100% WCL accuracy (if WCL even is 100% accurate... who knows).
The config menus are a bit confusing at first. I did not like having to do custom tags just to get the columns the way I prefer them (without the percentage). I prefer Skada's way of letting me uncheck the percentage column. It's not a biggie, but if you have two windows open (I really liked the Enemy window!), it can get crowded in the dps window.
As for the plugins that I used... the deathlog was a pleasant surprise. I will deinstall it, as Deathnote is still vastly superior, but for a small plugin it's not too shabby and will probably serve most people well. The charts plugin is going to get tossed, it's fugly, it's impractical because it's hard to distinguish between the lines and I have too few options to choose the data I wish to display. At least they weren't obvious to me. I really would have liked to have a graphical display for various things, Recount is really good at that despite all the other flaws it has and Skada goes the minimalistic road. So charts were a big plus. But not like this. And lastly, I tried the timeline plugin, now that is a real plus. Well done, practical and easy to use with almost the same functionality as WCL. Of course not with the same amount of options and tweakage but for in between fights, it's sufficient, going to keep that.
TL;DR:
Plus: Easy to switch from Skada, despite different UI approach. Accuracy seems to be alright, speed is fine. Did not encounter any bugs that I noticed.
Minus: Options can be confusing at first, is not included in ElvUI Addonskins, plugins need some work by the plugins authors, but when done can be a big plus.
Suggestion/Wishlist: Since I prefer analogue to digital when I'm just glancing at shit, I always prefer not to having to read stuff infight. Thus, I would really like an Option or a way to hide the damage/dps/percentage texts at least while in fight. Or even hide completely unless I mouseover. Often enough, especially in fight, I do not care if someone did 32.4k or 33.2k dps. I just need to know the gaps and the bars are quite enough to display that to get a rough picture if I'm underperforming or not. So basically, can you include an option for me to hide any text but the name tag in the bar, either just infight or completely unless I mouseover someone specifically, because I'm interested in him? Or both.
I'll get back when I notice something else worth mentioning.
