Issues with vim-ctrlspace and vim-airline

[aste4]

Weird behavior with vim-airline and vim-ctrlspace and let g:airline#extensions#tabline#switch_buffers_and_tabs = 1

Issue 1

With

let g:airline#extensions#tabline#enabled=1
let g:airline#extensions#tabline#show_tab_type=1
let g:airline#extensions#tabline#buffers_label='buffers-label'
let g:airline#extensions#tabline#tabs_label='tabs-label'
let g:airline#extensions#tabline#show_tabs=1
let g:airline#extensions#tabline#show_buffers=1
let g:CtrlSpaceUseTabline = 1

The tabline looks like this and works fine.

----------------------------------------------------------------------------------------------------------------
buffers-label | file1.txt | file2.txt                                               | tab 1 | tab 2 | tabs-label
----------------------------------------------------------------------------------------------------------------

With

let g:airline#extensions#tabline#enabled=1
let g:airline#extensions#tabline#show_tab_type=1
let g:airline#extensions#tabline#buffers_label='buffers-label'
let g:airline#extensions#tabline#tabs_label='tabs-label'
let g:airline#extensions#tabline#show_tabs=1
let g:airline#extensions#tabline#show_buffers=1
let g:CtrlSpaceUseTabline = 1

" delta
let g:airline#extensions#tabline#switch_buffers_and_tabs = 1

I expect the tabline to look like this. Also toggling the show_tabs and show_buffers would show/hide accordingly while keeping the positions the same.

----------------------------------------------------------------------------------------------------------------
tabs-label | tab 1 | tab 2 |                                             | file1.txt | file2.txt | buffers-label
----------------------------------------------------------------------------------------------------------------

Issue 2

Changing both show_tabs and show_buffers to 0,

let g:airline#extensions#tabline#enabled=1
let g:airline#extensions#tabline#show_tab_type=1
let g:airline#extensions#tabline#buffers_label='buffers-label'
let g:airline#extensions#tabline#tabs_label='tabs-label'
let g:airline#extensions#tabline#show_tabs=0
let g:airline#extensions#tabline#show_buffers=0
let g:CtrlSpaceUseTabline = 1

let g:airline#extensions#tabline#switch_buffers_and_tabs = 1

tabline looks like

----------------------------------------------------------------------------------------------------------------
tab 1 | tab 2 |                                                                                     | tabs-label
----------------------------------------------------------------------------------------------------------------

The problem is that making a change in the file changes the tab color to indicate there's a unsaved change. Undoing the change or even saving the file does not change the tab color back to indicate there are no unsaved changes

Issue 3

With below configuration where show_tabs=show_buffers=1 , the tabline is not visible at all. Ensuring only one of those is =1 shows the corresponding label but the label is on the right side

let g:airline#extensions#tabline#enabled=1
let g:airline#extensions#tabline#show_tab_type=1
let g:airline#extensions#tabline#buffers_label='buffers-label'
let g:airline#extensions#tabline#tabs_label='tabs-label'
let g:airline#extensions#tabline#show_tabs=1
let g:airline#extensions#tabline#show_buffers=1
let g:CtrlSpaceUseTabline = 1

let g:airline#extensions#tabline#switch_buffers_and_tabs = 1
