I noticed a lot of you have asked some questions, I’ll try to answer them as best as I can.

SenseiWarrior: SenseiWarrior: This is great, but will this ever become more customizable by allowing developers to configure a value from 0-1 similar to AnchorPoint? Outline would be 0, Middle would be 0.5, and Inset would be 1 for example.

We have no plans to add this right now, is there any reason you want to be able to do this? You can achieve a similar effect right now by parenting one GuiObject into another. The inner GuiObject would have a BorderMode of Inset, and the outer GuiObject would have a BorderMode of Outline.

SushiiDeluxe: SushiiDeluxe: Does this also work for circular GUI elements?

Nope, see @TheCarbyneUniverse’s reply

rachjumper: rachjumper: Can we see border transparency separated from background transparency too?

Since the transparency of the border is tied to BackgroundTransparency it is difficult to add this and remain backwards compatible. I’ll have a think about this since I’ve seen users request it before.

SelDraken: SelDraken: How do these “impact an object’s children”

The children will be padded by BorderSize when using BorderMode Middle or Inset.

Mariofly5: Mariofly5: So I had a thought about this. Is there a possibility of the borders obtaining their own ZIndex property?

ScytheSlayin: ScytheSlayin: Ooo! When can we make custom ones with decals or something?

Make a feature request!

ElliottLMz: ElliottLMz: Will we ever get native rounded borders?

Qxest: Qxest: Custom border radius when?

This is another commonly requested feature. See the following response:
