A user was asking me these questions privately on DIYC. The DIYC forum is acting up and it wouldn't let me post a response to the message so I'm posting it here since it may benefit others. I encourage everyone to ask questions publicly since it will give other users and developers a chance to help carry the load of answering questions as well as other users may have the same question.
----------------------
When you get a chance, can you answer some of these:
1. Is there any plans to have multiple effect changes? For example, I have 20 effects, I select them all and then apply or change parameters, like colors (similar to SuperStar and Vixen).
2. Does undo and redo not work? I have tried and it doesn't seem to work.
3. When I copy an effect, why doesn't it paste the same length?
4. I inserted an effect and then moved it and it "docked" into another. How do I undock or separate them? So far, I have to copy, then delete, then paste back.
5. It would be nice to be able to select multiple effects, then right click and have feature to set all to same length, same start/stop time, etc.
6. I'm tyring to mimic some of the effects that Vixen has, and can't seem to be able to do so. For example, I have a window, I want to start at the bottom left corner and chase clockwise with persistence, then once I get the window "filled", go back. I did this with curtain in Vixen, but curtain doesn't behave the same way, I guess because of how the models are built. In Vixen, the windows are basically 4 separate strings. Any guidance would be great.
7. On the fire effect, color changes don't work. Only hue shift.
8. What are playlists?
9. Anyway to have the sequence remember where I had zoom set, so when I open next time I don't have to do again?
--------------------------------------
1. There aren't really any plans. There are multiple developers and they just kinda do whatever they want. Sometimes it's a battle because one guys checks in changes that go against what someone else is trying to do. If you want a new feature it's best to enter an issue ticket on Github or people will forget about it.
2. There is no undo/redo feature anywhere that I know of.
3. A single effect paste will paste into the length of the selected cell. A multiple effect paste will paste them all with the original time lengths. Later I could see us having selectable modes "Paste by Time" and "Paste by Cell". So one developer did the single effect copy/paste and I did the multiple effect copy/paste so that's what we ended up with.
4. No way to unmagnetize effects yet. Either copy/paste or what I do is click the effect...delete it...then drag a new one down which will be an exact copy of the settings.
5. Yep a lot of things would be nice...do you write code?

6. I don't have window type models but there is a way to do what you want but it's clumsy. You gotta create a 2nd dummy model that's a straight line, map it to the same channels, and use it to drop the effect on. If the model is drawn as a square the effect is not going to display as if it's a single string it's going to display as if it's a matrix with no middle. Everything is modeled as a flat rectangle.
7. Sounds like a bug that needs to be logged.
8. I've never used the Playlists. You can use xLights to schedule and play your show but I always use the falcon Pi player.
9. Anything is possible. That's another enchancement request. I leave it up to the user's to create the enhancement tickets. If its something I want I just fix it myself.
You other question about the effect not updating is fully answered by my post on the xLights forum earlier today. Next release should have those improvements.
