For a $20/month program, it's really frustrating that I've tested it's limited capabilities multiple times.
1. Radial gradient: Should have the option to be deformed to shape. For instance, if I wanted a butterfly shaped radial gradient, the radial gradient should be able to act more like a proportional subdivision. Otherwise, the closes thing there is to what I'm looking for is the Gradient mesh because..

1. Gradient Mesh: The Gradient Mesh has a severe lack of customizability. Everytime I use that tool for any complex shape, I always get a jumbled mess of lines and subdivisions that are overlapping and completely chaotic. We should have the option to adjust the anchor points of the mesh, but that's impossible without warping the vector shape. The tool is a nightmare to work with and practically impossible to get the results I'm looking for. You should have the option to start with a simple perpendicular grid and freely adjust the curves and anchor points without altering the vector shape. If you're not going to allow for this simple capability then don't bother having the gradient mesh at all.

2. Free form gradient: The other alternative to a gradient mesh would be free form gradient. While this tool is definitely a lot better and more customizable than the gradient mesh, it's not without it's frustrating parts For one, it only ever allows you to draw curves. You can't do straight lines. between 3 points on the same line and there doesn't appear to be a hot key to allow for that capability. And simply using dots without lines turns the dots into radial gradients instead of a linear gradient when the points are connected by lines and you don't get the same effect. The tool is also incredibly tedious to use. Anytime I accidentally click a hotkey like Ctrl I for eyedropper it kicks me out of the tool, or I'll accidentally click an extra gradient dot instead of clicking on one that was already placed.

3. Linear Gradients: This tool is great, but just like with what I talked about in regards to a radial gradient tool, this tool has it's frustrating limits. For one, the gradient it produces is not at all constrained by the bounding box of the vector and it's impossible to accurately reflect the gradient of a shape with this tool. There should be an option to have the linear gradient warped to accurately reflect the shape. For instance, if I have a trapezoid with a base that is much larger than the top, I want the proportions of the gradient to be proportionate the length of the top side and the bottom side, that way it actually reflects how lighting on that object should be.

4. Multiple Linear functions: Still in regards to the linear tool, I really wish there was the ability to have multiple linear gradients affecting the same vector shape. This would be useful in examples like buildings. Imagine you're looking down the road through a city. Buildings farther from your view are going to appear brighter or darker than the buildings closer to your vision. (That would be one gradient). But than the tops of the buildings are also, more than likely, going to appear brighter than the bottom of the buildings because it's closer to the sky. In cases like these, it is extremely practical to have linear gradients overlapping.
   Another thing in regards to linear tools is the ability to transfer the same gradient to other objects. For example, to keep with the building example, the sun is setting on the horizon of the city and you see the reflections of the sun's light on the windows. The windows closer to the sun will have a brighter reflection than the windows closer to your view. But because all the windows are parallel to each other and are effected by the sun's reflections the same way, you should be able to draw a linear gradient from Point A to Point B and transfer those exact enpoints and slider coordinates to all the windows. I've been able to use the eyedropper tool to copy the colors in the gradient, but most of the time the length and location of the gradient line tool resets and I would have to manually manipulate the gradient lines to match for every single window and that's just plain time consuming and tedious not to mention it would not be a perfect continuity when it comes to accurately reflecting the window reflections.

When it comes to these additional features, I'm not asking you to completely get rid of the features that already exist as those are still useful applications, but all I'm asking is for all these tools to be customizable and as integral as possible. These numerous incapabilities is frustrating and stunts my creative process enough that I wish I could get a job at Adobe just to have these features added.
Thank you!
