currently there is only a func to find by classname, target and targeetname

why not a dynamic one ?
if im right this function should make it ( i cannot code C/++ but i think its correct)

static cell AMX_NATIVE_CALL find_ent_by_keyvalue(AMX *amx, cell *params)
{
	edict_t *pEnt = INDEXENT2(params[1]);

	int len, len2;
	char* sKeyName = MF_GetAmxString(amx, params[2], 0, &len);
	char* sValue = MF_GetAmxString(amx, params[3], 0, &len2);

	pEnt = FIND_ENTITY_BY_STRING(pEnt, sKeyName, sValue);

	if (FNullEnt(pEnt))
		return 0;

	return ENTINDEX(pEnt);
}

and would be called like this:

find_ent_by_keyvalue( ent , keyname , keyvalue )

or maybe even make one to find ents with given keyname without specifying keyvalue

[Freecode]

like this

int len;
	char* sKeyName = MF_GetAmxString(amx, params[2], 0, &len);
	char* sValue = MF_GetAmxString(amx, params[3], 1, &len);

We don't need this, we have FakeMeta:

EngFunc_FindEntityByString, // edict)    (edict_t *pEdictStartSearchAfter, const char *pszField, const char *pszValue);
