Tanks you for Shougo/ddu-ui-filer#3 and Shougo/ddu-ui-filer#5. But I found new bugs related to them.

Problems summary

There are 2 bugs about toggle of uiParams and resume of ddu-options.

When setting resume in ddu#custom#path_global(), there is bug: Shougo/ddu-ui-filer#5. But setting in ddu#start(), there is no bug (ddu restores the previous state as I expected).
When setting both resume and toggle, resume works well but toggle does not work.

Expected

If setting resume in ddu#custom#path_global()`, ddu restores the previous state.
toggle works with or without resume setting

How to reproduce the problem from neovim/Vim startup (Required!)

For the 1st bug.

Call ddu#start({})
On a directory, push <CR> to expand the directory.
Push q to quit ddu.
Call ddu#start({})

then you will see that ddu does not restore the previous state. But,

Set resume in ddu#custom#pach_global() v:false.
Call ddu#start({ 'resume': v:true })
On a directory, push <CR> to expand the directory.
Push q to quit ddu.
Call ddu#start({ 'resume': v:true })

then you will see that ddu restores the previous state.

For the 2nd bug.

Call ddu#start({ 'resume': v:true })
Call ddu#start({ 'resume': v:true })

then, you will see that ddu-ui-filer still open. But,

Call ddu#start({})
Call ddu#start({})

then ddu close.

`toggle` and `resume` dose not work well. #20
