Found this ancient, forgotten task that was basically a QOL improvement.
Given that the feature would shorten the time of testing from some 10-15 minutes to 2, I left a comment mentioning that it would be immensely helpful.

!too long after, the report started seeing some traffic && the feature got actually implemented.
Checked the implementation as soon as I could.
- Speedup worked well regardless of platform.
- Slowdown /* which was never actually mentioned in the task as it wasn't crucial */ was also implemented, but the mobile phones were omitted, since the implementation would be too complex for the time allowed for the feature implementation. I was perfectly fine w/ it, as this wasn't actually necessary for those.

I left a proper comment, thanking for the feature implementation.

...then the lead tester chimes in, bitching about the lack of implementation of the slowdown on mobiles.

Got the same explanation as I mentioned earlier - too complex for the time allowed. Plus, the feature had other platforms in mind. Having it working on mobiles was just gravy.

Good call, lead, now - ask for another favor.
I'm sure it'll go well, since you can't be satisfied w/ getting what you need. You need that special pampering, too.
