Many people are still using the thick client, and this is the first interface user encountered about the tool. ALM is highly complex, and the strength of PTC Lifecycle manager is that it can relate items and related things. To handle such complex problem, the user interface and usability become highly important. Many of these annoyances do not rise to a very significant level, but collectively they are.
Currently, the client has many odd behaviors, time wasters, usability issues: A few examples:
cannot multilevel sort in multiple columns in query,
no custom order sort
cannot make filtering persistent in query (webclient can but does not support all functions)
cannot have one step "not" filter
"chain link" & "+" are opposite meaning, but people get used to it
"chain link" add is buggy
Easier way to show upstream/downstream traces
Easy way to navigate relationship
Zoom in/out features
Configure/ & oggle multiple views e.g. RM viewsets (since there're so much information to display) easily
Easy way to rename CM member
Easily hide & show information
If PTC can improve and enhance, it will go a longer way for btter user acceptance.
