As stated before, folder are going through a change and will be updated again soon.
As for your table column sizes you can add this css to your theme stylesheet that will allow you to control the widths:
#mdocs-list-table #batch { width: 1%; }
#mdocs-list-table { background: #fff; }
#mdocs-list-table .mdocs-sort-option, .mdocs-folders { cursor: pointer; }
#mdocs-list-table .mdocs-file-checkbox { width: 1%; }
#mdocs-list-table .mdocs-title { width: 15%; }
#mdocs-list-table .mdocs-description { width: 30%;}
#mdocs-list-table .mdocs-description p { margin: 0; }
#mdocs-list-table .mdocs-downloads { width: 12%; }
#mdocs-list-table .mdocs-version { width: 9%; }
#mdocs-list-table .mdocs-owner { width: 9%; }
#mdocs-list-table .mdocs-real-author { width: 9%; }
#mdocs-list-table .mdocs-modified { width: 15%; }
#mdocs-list-table .mdocs-rating { width: 10%; }
#mdocs-list-table .mdocs-download { width: 12%; }
#mdocs-list-table .mdocs-file-size { width: 10%; }
Thanks so much for the help. Don’t get me wrong all in all mdocs is an awesome plugin that we rely on. Thanks for all of your hard work.
