Version 1.5.5 has been out long enough for the suggestions to settle into patterns. This is a running collection rather than a formal changelog; once enough points have accumulated, they will be reviewed together for the next round of adjustments.
PDF zoom that does not follow the page
Within a single PDF, different pages sometimes need different fit-to-window scales. At the moment the viewer seems to take the zoom level of whichever page happened to be open first and apply it throughout. Each page should be handled on its own terms instead.
History text ignores the global setting
In the history list, file names do not respond to the global text-size setting. Change that setting and the history entries stay exactly as they were.
The collapsed sidebar loses its labels
When the sidebar is collapsed, the history documents entry disappears and its icon turns into a question mark. Hovering over the icon shows a folder symbol but no name. The suggestion is to keep at least the first one or two characters of the folder name visible when space is tight.
That request points to a simpler fix: the collapse button is being removed. The sidebar width can already be adjusted by dragging, and the collapse control was not doing much useful work.
Back should return to where you were
In the document library, if you are on page 3, open any PDF, and then press back, you land on page 1 instead of page 3. Search results behave the same way.
Favorites need a permanent place
Favorites are currently kept on the home page, which makes them awkward to use. After opening one favorited PDF, getting to another means switching back to the home tab. The request is to move favorites into the sidebar and allow custom groups.
A typical arrangement would be one group for frequently used standards, one for frequently used atlases, and one for project-related material such as land condition letters and survey documents. In daily work, most switching happens between favorites and history; the large category libraries are visited less often.
Bookmarks and the document tree
The file outline should sit at the top with small buttons. Bookmarks currently take up a separate column and do not even show the file name. The suggested model is the Jianbiao library, whose layout offers a fuller set of functions and makes searching easier. Standards and atlases could follow that kind of interface, with a tree that can be searched downward.
More items will be added as they arrive. The list is meant to be acted on in batches, not one comment at a time.
