It would be a fantastic feature to be able to save different 'layer themes' and be able to toggle between them. A layer theme would control which layers are visible and not visible.

EG: You have a file set up with 20 layers. Theme A has layers 1, 2, 5, 19, 20 visible. Toggle to Theme B it has layers 1, 3, 9, 15, 18 visible. The user can create a new theme from whatever the status of the layer panel is, then can quickly toggle between these different layer visibility settings. The layer themes can have custom names set by the user. This would save time immensely by containing potentially different print or export layouts within the same file. These could be linked to the export window allowing for a single export of the same artboard with different art. HUGE time saving and cuts down on the requirement for multiple files .

I have used illustrator for 15+ years and gained numerous grey hairs because of it. One thing that has constantly driven me insane is this:

You have in your illustration some elements that are fill only. Other elements that are strokes only.

You are busy with the eyedropper tool. Recolouring your artwork, trying out ideas.

If I select a stroke only item, that has no fill, please use a couple simple lines of code to switch the tool bar swatch thingy to focus on stroke. Similar to pressing X on the keyboard. And vice verse with a fill only item.

Why would I select a stoke only item and then want to add a fill to it?! Especially if it's a two point straight line!!!! Why not add a tiny line of code to recognise item selected has no fill, item has stroke, item has no closed path = switch swatch focus to stroke so user doesn't go insane.

Same with filled objects. If I wanted to add a stroke to it, I would do so manually with stroke menu. I wouldn't expect to add a stroke when using the eyedropper tool to change the fills colour.

It is so so annoying. Does no one at Adobe use illustrator all day long? It has contributed to my stress over the past 15 years.

Yes I can press X, shift X or /.... but it slows things down and I often to forget.

Also the recolour tool... make it for the year 2020. Give us curves to adjust artwork tones. When working in RGB, for artwork that will be later animated in afterEffects, we're less interested in individual swatch spot/process colours and more interested in being able to adjust colours with precision: levels, curves etc. Please I beg you.

We need a way to quickly transfer appearance from one object to another.

For now there are several ways to do it.

1. Grab the Eyedropper tool. Go to tool’s options. Set both Appearance check-marks. Select the art you want to apply appearance to and click the one you want to copy appearance from with the tool (or vice versa with a proper modifier held).
   This one requires me to go to the options before to set these check-marks and go there after to turn them off, because I don’t need these by default.




2. Save a graphic style from the object you need to copy it and apply it to the target one.
   This requires to save a temporary style and delete it after. Still, is the fastest method for now.




3. Open Layers panel, click Locate button (which still doesn’t have a hotkey but can be recorded in an action, at least), grab the appearance filled circle marker and try to drag it over with the Alt held the target one, but not the object on the canvas, but the item in the same panel... the one you can’t locate now, because you have to locate both items. This is quite simple when you have, say, two object on your canvas, but is tough when your art has hundreds of objects.




4. Copy an object you want to grab your style from and command Paste Appearance with the target object selected. The most easiest one.... wait... we don’t have it in Illustrator.

Because there is none.
And we can’t make it via scripting, because scripts can’t create or copy graphic styles, which we could have used to emulate method 2 automatically. There are 2 requests about it:

https://illustrator.uservoice.com/forums/908050-illustrator-desktop-sdk-scripting-issues/suggestions/35703022-graphicstyle-aspect

So I’d like to see all of these implemented.
