Move it into an <h2>Data Access</h2> in the usual place, after Methods and before Credits, and add pointers to the Table Browser, the Data Integrator and the REST API, plus the maf* and bigWig* command line tools. 134 pages: 55 had a download block that was moved and labeled, 56 get a list built from hgdownload directories that were checked to exist, 21 have no download directory of their own and so get the Table Browser and API pointers only, and 2 already had a Data Access section that was reworked. Existing download lists are unchanged apart from http -> https and an added target="_blank". Wording follows what each track actually holds, so the alignment-only pages do not claim conservation scores and the Data Integrator is only mentioned where it can really be used, since it does not handle MAF. Also corrects one link: hg18 cons44way pointed at multiz44way/maf, which redirects; it is now multiz44way/maf/.
