You are right, if you set "Maximum Page Links in Pagination" to a higher number it will not allow the "Jump To Page" dropdown to appear. If I set it to 2, then I need a thread with at least 4 pages for the dropdown to appear.
You can disable mobile version of paging by going to BootBB theme and editing responsive.css
Find ".pagination > .pagination_page," and remove it (with the comma after it).
After the edit the css block should look like:
.forumbit_subforums, .forumbit_moderators, .forumbit_description, .threadbit_rating, .threadbit_pagination, .forumdisplay_sorting_options, .pagination > .pages, .thead_links a span {
display:none;
}
Then you can increase "Maximum Page Links in Pagination" above 5 for more page links. But in this case you also need to edit global.css and find this block:
.pagination {
....
}
edit it to look like this:
.pagination {
font-size: 78.6%;
padding-top: 10px;
margin-top:9px;
margin-bottom: 5px;
line-height: 2.3;
}
I will include these changes in the theme on the next release.
