I think the system as it stands has a number of issues that ought to be addressed.
First and foremost is the Alt key needs to renew the blue glow whenever you press it, because hidden levers in dark dungeons are the literal equivalent of my favorite line from Hitchhikers Guide to the Galaxy ( every time you push one of these little black buttons labelled in black on a black background a little black light lights up black to let you know you've done it!)
Second is the issue highlighted in the crypt where I can spot one gargoyle head trap but somehow am unable to deduce the rest are also the exact same trap. I think Perception should have a much bigger radius (like 15m in light, 10m dim, 5m dark), and follow 5e to be passive. That automatically means if I see one, I see them all, saving the frustration of attempting 8 checks with 10% fail rate at max Wisdom and proficiency. That's a 57% chance to fail at least 1 under the best possible conditions, which is nuts. No rolling allows for higher DC which makes party role more important rather than just pulling all 4 of us over now I know I missed something.
Third is the issue of group fail flat out boning you. I haven't played long enough to know if BG3 works like Kingmaker where levelling up resets the check for you, but it really should. But also I'd like to have an active option with much lower range, much lower DC, and higher investment. As in, I toggle a button to actively search that halves movement speed, only searches 2m, but has a DC of 2. That way completionists don't feel the need to savescum, or drag a full party around every inch, and the "natural" roleplayers can just leave the button off.
And last, the failed alerts ought to be toggled in the Options. It's a divisive issue and both camps are hard to reconcile; some REALLY don't want to know and maintain replay value and others want to complete everything as they go and find dead ends MADDENING. In the end player choice is king, and the change shouldn't be overly difficult, even if the check stays in the log and only the graphic is hidden.
Anyway, just my 2 cents for a first post...
