Need for a more prominent indication of object being grabbed

Nobody has claimed this yet.

**Is your feature request related to a problem? Please describe.**
Today I checked how objects are picked up. I reach out to the sphere and press E (also left-click), but then I'm unable to confirm whether it's grabbed. I don't know what caused it: my relative position or angle of grabbing, maybe both. It didn't give any feedback that can be accounted as picking up object, other than a small dot in the center.

In doubt, I press said button again, and only then I understand it was picked up and that I just didn't try moving from the spot. At this point, object is already thrown/dropped. Remember: it simply happens in a blink of an eye, but I had to go through the same lapses again and again before realizing what was happening. Current feedback with jumping blue cursor happens very fast, which is barely noticeable.

**Describe the solution you'd like**
UI/accessibility feedback of grabbing an object the mere moments it's done with duration of **at least 200ms**. Show some particles or let cursor indicate in a more recognizable way that user actually grabbed the object.

**Describe alternatives you've considered**
I tried looking closely to the center - it's like a chore, because then I get distracted from surroundings. Personally, I'm just more confident in moving something if I can capture the whole picture in head, click the thing, and have a call to move.

**Additional context**
It may seem that issue is too trivial and not worth considering. However, if we remove the destructive physical feedback, in perspective, fixed UI solution adds a bone to every interaction that user makes. Also, good for recordings, where people watching don't interact and can't see current blue-dot feedback without excessively focusing on the center of view.

No implementation file or test is named. Start by locating the grab interaction and the current blue-dot feedback, then trace where the pickup event is presented to the player. Done means a successful grab produces clearly noticeable UI or particle feedback lasting at least 200ms.
