This gives the name of the park as Lands End in the  open outline,  not Lincoln park.
User phoen19 shoved the boundaries to the side in order to create her/his own little Lincoln park and grassy area, formerly engulfed by Llands End.
Are you familiar enough with the area to say anything about the nomenclature?
.
If you try Potlatch (usual flash disclaimer, obsollete) you will find it conflicts with your muscle memory forr kezboard shortcuts and lacks many user-friendly presets.
But f'rinstance, way history (key h) is far more convenient for a quick overview than the iD opening a separate OSM history page.  something i use a lot, so that habit causes me no end of annoyance when iD animates a help screen into view.
Plenty other differences - s == save, q == quadrilateralise(), w is noop (wireframe is found in pull-down menu, w/o colours) and e, I think of Entfernung, measures distances.
Overall it felt faster.  There are no intermediate zoom levels, only 1:1 tiles, no overzoom, but also no imagery processing options.
I partly rebuilt a bus line relationship that had been turned somehow to mincemeat (probably cutting the way every dozen metres or so to change lanes count) in one o' yer leftist-coast haunts nearby with no major issue apart from ignorance.  Clunky but it worked.
.
You may find Potlatch to be too basic or clunky, but like `vi' it dispenses with too much user-friendliness of `pico' and derivatives or whatever the Great Unwashed use on their tablets.
Documentation is available, but sketchy.  There are bugs I know of and work around.  Actually, it's Potlatch 1 docs I'm thinking of, wanting to know what to do about a pulsating red node when restoring a previous revision of a mangled object.
.
For the editing i've seen you do, you may be disappointed by Potluck, but I've not studied your work closely at all.  I used to do simple-minded edits with tunnel-vision on mapping missing simple buildings, for which it was fine.  So prepared to yearn for iD when you see but a small number of POIs and the rest as green dots/squares.  Also, no Notes integration.
.
Ideally I'd ask phoen19 what was intended behind her/his edits, replacing the large park with the small one.  What I will likely do is restore the original outline (with history) and let the overlapping parks serve to drive Pokémon away as I understand they do, as a starter.
But the nomenclature thing bothers me first...
