How about a contrib panel in the configuration section, listing only the contribs available for the version of SME running?
With the following links for each contrib(or batched at the top of the page for all contribs selected in the list):
How to, Download, Check, Delete, Install, Uninstall
"How to" - Linked to the How to Page for the contrib
"Download" - Downloads the contrib to the folder \contrib\[contribution]
"Check" - Enabled or autorun after download to run a checksum on the downloaded contribution
"Delete" - Enabled after download completes to delete downloaded contribution if check sum is bad or if the contribution is not needed or wanted
"Install" - Enabled only after check has completed, to prevent a bad download from contaminating the server
"Uninstall" - To remove a contribution that doesn't do what you thought it would, it happens.
If someone would create this dream panel at/for contribs.org as a contrib or integrated into the next revision/update I know at least 1 person who would be very happy, maybe more.
If there is already such a panel in existence.....where is it??
