Hi @Anonymous & @michaelpaiva
We are listening, and we take all of your feedback very seriously.
Hopefully I can help by sharing some of the projects we are working on. The ones that affect this thread, can be broken down into short, medium and longer term projects.
Short term - Text Height Groups
This feature will allow for the size of the text objects on a drawing to be re-sized, giving you more control over the size of objects, like dimensions, Balloons, tables etc. Reducing the size of the dimension text will reduce/scale down the size of dimension arrows.

Medium Term - Dimension Text Control (Leader Flip)
This feature will give you the ability to flip an arrow’s position, it will affect either a single side or both sides of a dimension. Bear with us, it will be a few months before you see this in the product, but it is coming.
Longer Term
Fusion drawings are created using ASME and ISO standards, the dimension styles in our drawings are set to comply with these standards. We want to add more flexibility in this area.
If you’d like to help shape this, I’d love to talk to you, here is a link to my calendar, please book a Zoom session with me, we can discuss your drawings (and challenges), and I can share our ideas, as well as more of the roadmap with you.
If you’re not up for a chat, but still want to be involved, please share examples of your drawings with me, I want to understand where you have issues, or where you have used workarounds to get the results you desire. The best way to do this, is to email me Clint. Brown {a} Autodesk.com.
