Please, pretty please... don't insult my intelligence like that.
I am not forgetting vanilla, I am not forgetting mods, I am not forgetting different playstyles, I am not forgetting different difficulties and I am not forgetting self-imposed restrictions.
Exactly the opposite... I considered them too and it only made it more obvious (for me) that the feature is fundamentally flawed... it is useful in such a measly percentage of cases above that it is practically useless.
Giving an example that it is useful in one or two highly specific cases, out of a virtually unlimited number of cases is also not going to convince anyone.
When it comes to changing the xcom UI, that stood the test of time (!), I will only make changes that I believe in... and which I believe can help at least 80% of players. I'm also not doing this alone... I consult the new UI features with modders, with people on discord and on the forum. And when I get negative feedback, I stop immediately. Even when I get 50% positive feedback and 50% negative feedback, it's a stop, because it's just not enough for a UI feature (for non-UI features, it's a different story). I don't have exact statistics, but my guess would be that only about 10% of UI features discussed were actually implemented, maybe even less. Moreover, also for UI features that actually made it in, I closely follow user reactions afterwards and follow big streamers like Yogs to see how intuitive and seamless it actually is. In my opinion, this particular feature helps less than 1% of players and annoys the rest. I may be wrong (like everyone else), but probably not wrong "enough". Lastly, this is not the first time feature like this was discussed, I remember similar discussion initiated by Starving Poet maybe 1 year ago, and before that by Ivan Dogovich probably about 3 years ago and before that by someone called Unknown Hero in 2014... all ending with conclusion "it creates more problems than it solves".
PS: also, nobody actually even tried to give concrete UI suggestions here... the feature is so vague right now, that you and me maybe have completely different idea in our heads how would it look like and what would it do (exactly)... so maybe someone should first present a solid proposal first
