One of the most convenient alignment features in illustrator is the 'align to key object', which Sketch doesn't support, making it difficult to align objects quickly. Please add that feature for XD.

Will be added Material Theme Editor?

Sometimes you need to reorganize your design system files. Once you have created a master components, you cannot move it to another file, and you are stuck with the current file forever.
It would be great if you can just move your Master Component from one document to another.

Apparently only JPG/PNG is supported when performing drag & drop of a set of images.
My assets are often SVG so supporting that format there would spare me from having to generate temporary PNGs or place manually.

It seems currently it adds all SVGs on all cells when dropping and creates a mask of all the files combined(??).

Thank you.

Transparent PNGs do not allow color edits. Editing fills will extend to the rectangular bounds, not just the object

Allow users to select Opentype features supported by a given typeface. This would be especially useful for anyone designing for ecommerce (tabular lining numerals), or text-heavy sites (small caps, proportional old style numerals), or rich typography in general (alternate stylistic sets, swashes, superscript, subscript, fractions). Common ligatures seem to be enabled already, but there's no way to access discretionary ligatures.

On the web, i often use line height to determin the height of the types container. Therefore the text should sit vertically centrally to its line height. This is different to how line height works in print.
I also use line height for vertical rhythm. see more info on this here:

vertical rhythm is a huge factor when I design for web

Stacking artboards can help to clear space for working and rearranging artboards.

Also we can stack artboards by size or type.

Making more complex vector drawings is difficult without a tool like the scissor tool from Illustrator.

Creating arches like the attached image in Illustrator is super easy with the combination of the scissor and circle tool, but in XD it is very difficult.

Ability to right-click to swap Symbols in Design mode
Or replace selected artwork with an existing Symbol

This request does NOT cover nested-symbol overrides (swapping an inner symbol differently in each copy of an outer symbol). For that, please upvote https://adobexd.uservoice.com/forums/353007/suggestions/19592509-nested-symbol-overrides

User should be able to use a soft return (shift+return) to break a line of text without adding paragraph spacing .

It's currently possible to round corners on primitive shapes. As soon as additional anchor points are added, or a shape is created from scratch using the pen tool, the ability to round corners is removed.

It would be nice to have this option at all times.

the ability to apply image filters and treatments such as "hue, saturation, levels, etc".

I would like to be able to wrap text around an object or another text block as with InDesign.

At the moment a locked object can still be selected, hindering the ability to select an object underneath.

It would be great if locked object would be completely disabled, similar to how an illustrator locked object behaves.

Allow an Overlay to be applied to another overlay. For example, you have a dialog box Overlay and inside you want to have a drop-down menu which has an Overlay of a list of options. Currently what happens is the drop-down Overlay replaces the dialog Overlay.

I think this is something fundamental that would make Overlays even more powerful. Its omission almost feels like a bug.

It's quite frustrating that every time I use the shape tools, I have to remove the stroke and change the fill.
Like in ID and AI, it would be useful if the object fill and stroke remembers the previous settings, or a default could be somehow set.

When you enter a width for an object, also be able to set the size using a percent.
