CodeLite IDE

Collapse All on workspace panel, it really Collapses All, i mean collapse all projects and leave workspace node expanded will be better.

Thanks, I have implemented this

code-lite ide version : 12.0.10
os:ubuntu 16.04LTS
when TiX was typed, completion tips should be TiXml..., but now only TIXML2_... and TIXML_... appears.
only sudo apt-get install libtinyxml-dev was done.

and another advise,
completion only action when the 3th char is typed.
so, if wrong char is type anywhere more than 3, completion items will disappear.
I have to backspace to 2 char left, and re-type right 3rd char, completion tips appear again.
I think this causing much inconvenience, do you agree?
If the completion tips appears at any position only if the leading chars is rightly typed,
it will becomes very convenient, right?

Its not about which packages are installed, do you have the correct include files in (something like #include <tixml.h>)
If the header containing the definition is included, than CodeLite should be able to parse it and offer completion.
Also, try reparsing the workspace from: Workspace->Parse workspace

thanks, after parsing workspace, it works.

Why are File->Save all files and Save As ... items always disabled even at more than one file is modified?
How to make them enabled ?

File->Save is always enabled, I am not sure why you say its disabled...

Which OS? and version?
